Apple push notification not working for distribution/ad hoc testing - ios

I have been using sandbox push notification for a while, and it is working perfectly. After switching to distribution, push notification stopped working.
Things that I have checked:
Two separate push notification certificates are created, one for development (Sandbox) and one for distribution(production).
Device token is different for sandbox and production.
We use NotNoop APNS on server side. The certificate.p12 is created by exporting the private key under push notification certificate in Apple Keychain Access. Certificate itself is not in the p12 file.
Checked archived package for production with command
codesign -d --entitlements :- "Payload/YourApp.app"
And the code signing entitlement is distribution.
Followed Apple TN 2265 (https://developer.apple.com/library/ios/technotes/tn2265/_index.html). While using openssl to connect to APNS, the connection is closed right after handshake (for production). For sandbox, there is a pause after the handshake, and then more reads & writes.
My command:
> openssl pkcs12 -in Cert_prod.p12 -out Cert_prod.pem
> openssl s_client -connect gateway.push.apple.com:2195 -cert Cert_prod.pem -debug -showcerts -CAfile "Entrust.pem"
The output (for production):

Therefore, it seems that the broken link is between my server and APNS. How can I know why the connection is closed?
I suspected that something is wrong on the certificate, but could not find anything. I took the same steps to create sandbox certificates, and they worked just fine. Did I miss anything for production?
Other related links that I checked:

http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1
Couldn't able to connect to APNS Sandbox server

The certificate.p12 in NotNoop APNS should be exported from the certificate only, without the private key. In Keychain Access, click the small arrow next to the push notification certificate to show the private key, select the certificate only (without the key), and export it to a .p12 file. Updating the file on server solved my problem. Openssl is a good tool for smoke test before archiving the app and running it in ad hoc mode.

How to get to know TCP or UDP protocol from wireshark pcap hexadecimal view

A sample TCP hexadecimal Wireshark capture shown below,
0000 6c 6a 77 8d 48 cf 96 38 a7 7d 02 de 08 00 45 28

How to get to know TCP or UDP protocol from Wireshark pcap hexadecimal view ?.
Save the hex data, as shown, into a text file and then run text2pcap file.txt file.pcap. You can then load the file.pcap file into Wireshark. Run text2pcap -h for more help or refer to the text2pcap man page for more details about that tool.
0000 6c 6a 77 8d 48 cf 96 38 a7 7d 02 de 08 00 45 28
0010 00 34 56 92 40 00 28 06 fa e9 a2 7d 13 09 c0 a8
8th Byte in the second line we have to check. In here it's 06. So protocol number 06 is TCP. Like wise we can get to know the protocol number from hexadecimal view.

SmardCard is supposed to sign and return data with signature (Certificate). It should be a string that I need for later but when I try to convert it back to string all I'm getting is vC~ÄoÁ;ú¤O³H÷-Ïà÷6§¯±µhТ´6ÑÄk16XHº »¹5 w_ªK©$o_oLL kind of a string that I can't actually use. Am I doing something wrong or missing any steps in between? How am I supposed to get that string from that hex response? Do I need to reverse bytes maybe (tried)?
Thanks in advance!
You are converting the returned data into a WideString (default string type in modern Delphi versions) but the returned data is actually in AnsiString format.
And if you want to view the returned data in a similar fashion that most browsers show digital certificate key value just add an empty space after every two characters.
For this you can use code like this:
//AStr is of AnsiString type
for I := Length(AStr)div 2 downto 1 do
begin
Insert(' ',AStr,I*2+1);
end;
The returned result will then be:

What are these weird ha:// URLs jenkins fills our logs with?

We noticed our Jenkins build logs were being filled with 10 times more content than we expected. This greatly increases the amount of logs that slaves have to send back to the master, which in turn makes all builds take longer, which in turn makes builds fail with spurious timeouts.
On investigation, we find the lines all have a huge URL prepended.
ha:////{320 bytes of base64 junk} Log message
ha:////{320 bytes of base64 junk} [blank line]
ha:////{320 bytes of base64 junk} Next log message
I tried decoding the base64, but it doesn't produce any structure which I'm familiar with.
I didn't want to post ours because someone who knows how to decode it might find private info in there, but I tried searching for some of the content we were seeing, and noticed that someone else had posted the same sort of thing to pastebin:
https://pastebin.com/LM7mht8W
Taking one of those URLs:

So it kind of seems like the timestamper plugin is somehow implicated in this nonsense, but when I go and read their code, I don't see anything about this stuff.
Which bit of Jenkins is actually doing this, and is there a way to avoid it?
Good detective work, #Trejkaz. Disabling the timestamper plugin did NOT fix things for me (I left the plugin installed; perhaps I should have removed it altogether or restarted Jenkins one more time to be sure).
My best answer (the one I'm using in practice) gets rid of all the escape sequences in the console AND in the context of this question, removes all of the 'ha:////' URLs as well so I get pretty close to unadorned, complete ASCII text in my processed console log. It's worth mentioning that our site's automation culture is to allow Jenkins builds to expire except those marked for keeping, so my workflow is to produce a postprocessed console log artifact to "keep" and not to archive the original log. It's not to create a smaller log in the first place, which I saw as more time- and resource-consuming for no discernible benefit.
Presuming the raw Jenkins console log lives in console-log.txt, it's:
ansi2txt < console-log.txt | col -b | sed 's;ha:////[[:print:]]*AAAA[=]*;;g'
This eliminates escape sequences meant to provide terminal display sugar without requiring build and installation of tool packages not found in any repo (in Ubuntu ansi2txt comes from colorized-logs and col comes from bsdmainutils), removes the mysterious 'ha:////' URLs regardless of their source, and turns a raw console log that looks like:

which is the same as what I see in the Jenkins web interface when browsing the console log.
I hope this answer helps you in a practical sense (i.e. rather than making an O(n) walkthrough of all of your plugins searching for the 'ha:////' culprit).

How do I get public key hash for SSL pinning?

How would I get the hash of a public certificate's info to be able to perform SSL Pinning in my application?
I am using TrustKit in my iOS application and it is asking for me to set the hash that I am expecting. Where can I get this from?
Since this is a programming web-site, i wanted to explain how to calculate the public key hash for Public Key Pinning. This is important because the algorithm is completely undocumented. (It's not even documented by the canonical RFC 7469 Public Key Pinning Extension for HTTP ! The RFC simply says "Use OpenSSL". That is a non-answer.)
tl;dr: Base64(SHA256(SubjectPublicKeyInfo))
A Certificate is not (just) a public key
The first important thing to realize is that a public key is just a number (e.g. 2,048 bit number for RSA). A certificate is a collection of a lot of additional information (subject names, hashes, digital signatures).
This means that:
a public key is a number
a certificate associates a web-site with that number (e.g. stackoverflow.com)
A public-key pin contains a hash of the public key. It is not the hash of the certificate. This lets you renew certificates while keeping your same public key.
The Certificate structure
We need to extract the public key from a certificate, so we need to know its structure. The structure of a certificate is documented (horribly) in RFC 5280 - Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile
In programming terms, a Certificate is:
struct Certificate {
TBSCertificate tbsCertificate,
AlgorithmIdentifier signatureAlgorithm,
BITSTRING signatureValue
}
And it's the SubjectPublicKeyInfo inside the tbsCertificate that contains what we're after:
struct TBSCertificate {
EXPLICIT version,
CertificateSerialNumber serialNumber,
AlgorithmIdentifier signature,
Name issuer,
Validity validity,
Name subject,
SubjectPublicKeyInfo subjectPublicKeyInfo,
//...optional extra stuff...
}
We need to take the SHA256 of the raw subjectPublicKeyInfo.
digest = SHA256(certificate.tbsCertificate.subjectPublicKeyInfo);
That value, base64 encoded, becomes the value we put in our web-server response headers:
String pin = String.Format("max-age=%d; pin-sha256=\"%s\"",
31536000, //1 year
System.Convert.ToBase64(digest));
response.Headers.Add("Public-Key-Pins", pin);
For example:
Public-Key-Pins: max-age=31536000; pin-sha256="hUIG87ch71EZQYhZBEkq2VKBLjhussUw7nR8wyuY7rY=";
But what do i actually hash?
As an example of calculating the PKP SHA256 hash, i am going to use the current certificate of Facebook.com. You can browse to Facebook, view the certificate, and save it in a base64 encoded DER PEM:
Facebook.cer (PEM DER ASN.1 encoded)

Which is a lot
But the only part we care about is the SubjectPublicKeyInfo:

If you take just those bytes:
30 59 30 13 06 07 2a 86 48 ce 3d 02 01 06 08 2a 86 48 ce 3d

9c 4f dc 73 a9 b3 49 2d a0 76 d3
And run them through SHA256, you get:
SHA256: 854206f3b721ef511941885904492ad952812e386eb2c530ee747cc32b98eeb6 (hex)
You then base64 encode that, and you get:
base64: hUIG87ch71EZQYhZBEkq2VKBLjhussUw7nR8wyuY7rY=
That is the hash that you add to your HTTP response headers:
Public-Key-Pins: max-age=31536000; pin-sha256="hUIG87ch71EZQYhZBEkq2VKBLjhussUw7nR8wyuY7rY=";
Cross-check
Our calculated values matches the PKP hash that SSL Labs returns:
You can also paste the original PEM (base64) encoded certificate into https://certpins.appspot.com/pin and confirm that it returns the same PKP hash:
Public-Key-Pins: max-age=31536000;
 pin-sha256="hUIG87ch71EZQYhZBEkq2VKBLjhussUw7nR8wyuY7rY=";
Why SubjectPublicKeyInfo?
A public key is a number (or in the case of RSA a pair of numbers):
exponent (e.g. 65,537)
modulus (e.g. one hundred and fifty four million googol googol googol)
Over the years there are a number of ways of storing these two numbers:
SHH:
[lenghPrefix]ssh-rsa[lengthPrefix][exponent][lengthPrefix][modulus]

PKCS#1 chose to use the DER flavor of ASN.1 encoding of the following structure:
RSAPublicKey ::= SEQUENCE {
modulus INTEGER, -- n
publicExponent INTEGER -- e
}
Later when new public key encryption systems came along, they "borrowed" the RSAPublicKey structure, but prefixed it with an Algorithm ID:
SubjectPublicKeyInfo ::= SEQUENCE {
algorithm AlgorithmIdentifier,
subjectPublicKey RSAPublicKey }
Where AlgorithID for PKCS#1 RSAPublicKey is 1.2.840.113549.1.1.1, which comes from:
1 - ISO assigned OIDs
1.2 - ISO member body
1.2.840 - USA
1.2.840.113549 - RSADSI
1.2.840.113549.1 - PKCS
1.2.840.113549.1.1 - PKCS-1
This format would then appear in base64 encoded files as:
-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----
This is the SubjectPublicKeyInfo that you get the sha256 hash of.
Inside every certificate is a SubjectPublicKeyInfo; even a Windows EFS certificate.
You can use OpenSSL to:
extract the SubjectPublicKeyInfo chunk and save it as a BEGIN PUBLIC KEY file
hash it
base64 it
People need to stop treating OpenSSL as a magical crypto box. Too often, people just type in esoteric openssl commands to do something, rather than understanding what they're doing. Even the very RFC on Public Key Pinning doesn't bother to explain what it is, and just tells you to go to the all-knowing openssl. OpenSSL is not the be-all and end-off of encryption management.
If it is a public website, you can use SSL Labs server test which computes and displays the pin.
The Public Key Pinning page over at the Mozilla Developer Network also has commands for obtaining the pin from a key file, a certificate signing request, a certificate or a website (this is the one in #mylogon's answer).
There is a really straight forward way of doing this. I spent some time scraping things together on this one to produce a very reusable solution. Unfortunately, I have only done this on OSX, but you should be able to follow along fairly easy if you're on another OS.
For this method you are going to need:
Install Homebrew
OpenSSL (brew install openssl in terminal after installing Homebrew)
Create new .sh file and set contents to be:
openssl s_client -servername $1 -connect $1:443 | openssl x509 -pubkey -noout | openssl rsa -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64
Save file to disk
From terminal window, call bash <new sh file directory> www.google.com
This should now return the hash that you require and leave you with a nice little reusable solution. You may have to press ctrl+c after the hash is returned.
It should leave you with something like the following:
Hope this helps someone out.
Thanks
Assuming you have openssl and the certificate file, you can use this command taken from here.
openssl x509 -in my-certificate.crt -pubkey -noout | openssl pkey -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64

Connect to Windows SQL Server 2008 R2 from Rails app

My Rails 4.2.1 app has to connect to a Microsoft SQL 2008 R2 database. I am using the tiny_tds gem version 1.0.4. FreeTDS v1.00.15 is installed on the production server running Ubuntu 14.04.
I run queries inside an each loop and I can't get the loop to complete, the process crashes before completion.
I tried playing with tiny_tds options without success.
Here's the code I am using to get the tiny_tds client (check tds_version and timeout options):
client = TinyTds::Client.new(username: db_conf['username'], password: db_conf['password'], host: db_conf['host'], port: db_conf['port'], database: db_conf['database'], tds_version: '7.3', timeout: 15000, appname: 'ERP')
Here's the FreeTDS log after such an error happens.

Any idea what I should do to fix those Unexpected EOF from the server errors?
In your FreeTDS configuration (often in /etc/freetds/freetds.conf as in your configuration), change the value of text size:
text size = 4294967295
That's the maximum value, IIRC. I believe with FreeTDS 0.91 that your default is probably 64512.
Looking at the SQL Profiler, I found out the Rails application was opening way too many connections on the MSSQL server. Upon reaching its max number of open connection, the MSSQL server refused opening any new connection, resulting in the Unexpected EOF from the server error.
To solve the issue, I had to reuse my open connection when sending queries instead of opening a new connection for each query. I guess this is the correct way to use the tiny_tds connector anyway.
Translated to code:
def self.get_pmi_client
if ##pmi_client.nil? or !##pmi_client.active?
db_conf = Rails.configuration.database_configuration["pmi_#{Rails.env}"]
##pmi_client = TinyTds::Client.new(username: db_conf['username'], password: db_conf['password'], host: db_conf['host'], port: db_conf['port'], database: db_conf['database'])
raise MSSQLConnectionError, t('erp.errors.pmi_connection_error') unless ##pmi_client.active?
end
return ##pmi_client
end
