RSA padding scheme

Greetings everyone! As I understand, such asymmetric ciphers as RSA and/or ElGamal requires strong padding applied before message is encrypted. Message is of course the one-time session key, used to encipher the actual data. There are different versions of PKCS#1, NESSIE, OAEP and other schemes
