How to override the default encrypted property prefix/suffix? - jasypt

Question

Jasypt expects encrypted properties to be wrapped with "ENC(...)".
I'm looking for a way to override the default jasypt encrypted property prefix and suffix with a custom ones like "secure[...]".
Is there a way to achieve this?

Answer 1

If you use pure jasypt library it is required to write your own version of existing EncryptableProperties as default one supports only ENC( as prefix and ) as suffix.
public class EncryptableProperties extends Properties {
private final String prefix;
private final String suffix;
private final StringEncryptor encryptor;
public EncryptableProperties(final Properties defaults, final StringEncryptor encryptor,
final String prefix, final String suffix) {
super(defaults);
this.encryptor = encryptor;
this.prefix = prefix;
this.suffix = suffix;
}
public EncryptableProperties(final Properties defaults, final StringEncryptor encryptor){
this(defaults,encryptor,"ENC(", ")");
}
#Override
public String getProperty(String key) {
String value = super.getProperty(key);
return decode(value);
}
private String decode(String value) {
if (value == null) {
return value;
}
String decryptedValue = value;
if (value.startsWith(prefix) && value.endsWith(suffix)) {
int start = prefix.length();
int end = value.length() - suffix.length();
String encryptedValue = value.substring(start, end);
decryptedValue = encryptor.decrypt(encryptedValue);
}
return decryptedValue;
}
}
Usage:
Properties encryptableProperties = new EncryptableProperties(properties,stringEncryptor,"CUSTOM_PREFIX(",")");
If you use spring boot integration
You could do this by using following two properties
jasypt.encryptor.property.prefix
jasypt.encryptor.property.suffix
Default one is:
jasypt.encryptor.property.prefix=ENC(
jasypt.encryptor.property.suffix=)
These properties are available with following library
