I have a system that an supposed to give my partner a public key to decry-pt the text. What I want is how to sign that text using my private key. This is how am doing it but it has failed.
require 'openssl'
require 'base64'
require 'digest/sha1'
#date = Date.today.strftime("%m/%d/%Y")
text_to_sign = "#{#order.phone_no}" + "#{#order.name}" + "#{#order.pay_type}" + "#{#order.pay_type}" + "1" + "MABIRA" + "81W30DI846" + "#{#date}" + "PULL" + "1" + "#{#cart.total_price}" + "#{#order.phone_no}" + ""
cipher = OpenSSL::Cipher.new 'aes-256-cbc'
cipher.encrypt
cipher.key = cipher.random_key
cipher.iv = cipher.random_iv
encrypted = cipher.update(text_to_sign) + cipher.final
private_key = OpenSSL::PKey::RSA.new(File.read('Private.key'), password)
ciphertext = private_key.private_encrypt(encrypted)
ciphertext.encoding
signed_text = Base64.encode64(ciphertext).gsub("\n", '')
puts signed_text
signed_text

Hi I followed the upwork developers site and the twitter oauth signature generation document and I did the following:
timestamp = int(time.time())
nonce = ''.join([str(random.randint(0, 9)) for i in range(30)])
url = 'https://www.upwork.com/api/auth/v1/info.json'
quoted_url = quote('https://www.upwork.com/api/auth/v1/info.json')
to_hash = 'GET' + '&' + url + '&'
param_string = 'oauth_consumer_key=' + UPWORK_KEY + '&oauth_nonce=' + nonce + '&oauth_signature_method=HMAC-SHA1&oauth_timestamp=' + str(timestamp) + '&oauth_token=' + ACCESS_TOKEN + '&oauth_verifier=' + UPWORK_VERIFIER
to_hash += quote(param_string)
hashed = hmac.new(UPWORK_SECRET + '&' + ACCESS_TOKEN_SECRET, to_hash, hashlib.sha256).hexdigest()
r = requests.get('https://www.upwork.com/api/auth/v1/info.json?oauth_consumer_key=' + UPWORK_KEY + '&oauth_signature=' + hashed + '&oauth_nonce=' + nonce + '&oauth_signature_method=HMAC-SHA1&oauth_timestamp=' + str(timestamp) + '&oauth_token=' + ACCESS_TOKEN + '&oauth_verifier=' + UPWORK_VERIFIER)
r.text
But when I do this, I get:
u'{"server_time":1472207775,"error":{"status":401,"code":401,"message":"Verification of signature failed."}}'
However the following works fine:
client = upwork.Client(UPWORK_KEY, UPWORK_SECRET, oauth_access_token=ACCESS_TOKEN, oauth_access_token_secret=ACCESS_TOKEN_SECRET)
client.auth.get_info()

Any ideas on what I'm doing wrong?
Thanks to the answer by #Blairg23 here, I figured out the following solution:
url = 'https://www.upwork.com/api/auth/v1/info.json'
auth = OAuth1(UPWORK_KEY, UPWORK_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
r = requests.get(url, auth=auth)
r.text
Just using an already-implemented version of oauth saves you a huge headache.

I am getting a syntax error when I am using if statements inside the data I am sending to asana. I am very new at rails and not sure what I am doing wrong.
This is the error:

I want to convert a string to a byte array before I can sign it with a private key but I have not done it before. My code is as below could anybody give me a clue on how I can do it. Thank you.
require 'openssl'
require 'base64'
require 'digest/sha1'
#date = Date.today.strftime("%m/%d/%Y")
text_to_sign = "#{#order.phone_no}" + "#{#order.name}" + "#{#order.pay_type}" + "#{#order.pay_type}" + "1" + "MABIRA" + "81W30DI846" + "#{#date}" + "PULL" + "1" + "#{#cart.total_price}" + "#{#order.phone_no}" + ""
password = 'secret'
#converting the string to byte array
byte[] buff => new byte[1024]
text = buff.text_to_sign
private_key = OpenSSL::PKey::RSA.new(File.read('Private.key'), password)
ciphertext = private_key.private_encrypt(text)
ciphertext.encoding
signed_text = Base64.encode64(ciphertext).gsub("\n", '')
puts signed_text
signed_text
Ruby has the bytes method and you can convert that to an array with to_a
http://www.ruby-doc.org/core-1.9.3/ARGF.html#method-i-bytes
string = 'some string'
byte_array = string.bytes.to_a
# [115, 111, 109, 101, 32, 115, 116, 114, 105, 110, 103]
I am designing a system in ruby on rails but I want to know how I can sign a text string using a private key. I am supposed to first encode text using ASCII byte array, then compute byte array hash value using SHA1 from a byte array, sign byte array of the hashed array using the private key, and then convert the signed array into base64 . This how am doing it.
require 'openssl'
require 'digest/sha1'
#date = Date.today.strftime("%m/%d/%Y")
text_to_sign = "#{#order.phone_no}" + "#{#order.name}" + "#{#order.pay_type}" + "#{#order.pay_type}" + "1" + "MABIRA" + "81W30DI846" + "#{#date}" + "PULL" + "1" + "#{#cart.total_price}" + "#{#order.phone_no}" + ""
password = 'mypassword'
hashed_text = Digest::SHA1.hexdigest(text_to_sign)
private_key = OpenSSL::PKey::RSA.new(File.read('Mabira.key'), password)
ciphertext = private_key.private_encrypt(hashed_text)
signed_text = [ciphertext].pack('m*')#encoding in base64
puts signed_text
signed_text
Any assistance is welcome.
I can't set the item summary in set express checkoput. L_NAME0=A caused error
def strUsername = "***"
def strPassword = "***"
def strSignature = "***"
def strCredentials = "USER=" + strUsername + "&PWD=" + strPassword + "&SIGNATURE=" + strSignature
def strNVPSandboxServer = "https://api-3t.sandbox.paypal.com/nvp";

Try updating def strAPIVersion = "56.0" to def strAPIVersion = "76.0" I think the advanced features a not available in the 56 version. I used the default set by Paypal as a test
