Error description

  • Error Description
    SI 5.2.6.3_12
    After IBM Sterling Integrator upgrade from 5263_10 to 5263_12,
    the Subscriber Keys
    validation for EBICS is no longer working on SHA1 or SHA256 for
    activating the EBICS user.

Problem summary

  • Users Affected:
    All
    
    
    Problem Description:
    Provide a property to ignore or consider leading zeros while
    calculating hash value of RSA.
    
    
    Platforms Affected:
    All
    

Problem conclusion

  • Resolution Summary:
    A code fix is provided.
    By default, the rsaHashKeyCompliant property is false.When set
    to false, it generates the SHA-256 hash value for RSA keys, by
    concatenating the exponent with blank character and the modulus
    in hexadecimal representation (using lower case letters).The
    resulting string is then converted into a byte array based on US
    ASCII code.
    When set to true it generates the SHA-256 hash value
    for RSA keys, by concatenating the exponent with ablank
    character and the modulus in hexadecimal representation (using
    lower case letters) without leading zero (as to the hexadecimal
    representation).The resulting string is then converted into a
    byte array basedon US ASCII code.To change the property, set
    rsaHashKeyCompliant to true and restart the server.
