I am attempting to write C code using the openssl libraries to decrypt data that has been encrypted by the Java function OpenSSL.encrypt(). I know the password, but I have not been able to figure out the parameters for PBE.
I am attempting to use the EVP_BytesToKey() function, but I don't know which algorithm to use (MD2, MD5, SHA1?) or how many rounds to properly derive the key and iv from the password. Everywhere I have looked says the Java function is compatible with "openssl enc", but I can't find what parameters it uses either.
I have also looked at PKCS#5, which is what is supposedly implemented, but it doesn't specify a default for algorithm or number of rounds. Please help!
Edit: Nevermind, finally found parameters that work - MD5 with one round.
