My RoR server receives a string, that was encrypted in C++ application using des3 with base64 encoding
The cipher object is created so:
cipher = OpenSSL::Cipher::Cipher::new("des3") cipher.key = key_str cipher.iv = iv_str
key_str and iv_str: are string representations of key and initialization vector for encryption algorithm. They are the same for RoR and C++ application.
The code on the RoR side is following:
result = "" result << cipher.update( Base64.decode64(message) ) result << cipher.final
After executing the last line of code, i get an exception
OpenSSL::CipherError (bad decrypt)
What is wrong here ? Any ideas ?
