2048-bit RSA Functions.

This group of functions is used for 2048-bit RSA. / /@{*/ / 2048-bit RSA PKCS1 V1.5 encryption.

The message * m - is encrypted to a ciphertext returned in * c - .

• c - The generated 256-byte ciphertext.
• m - The message to be encrypted.
• mlen - Length of * m - . 0 <= * mlen - <= 245.
• seed - The random seed to be used for the padding.
• slen - Length of * seed - . * slen - >= 253 - * mlen - .
• pk - A valid 2048-bit RSA public key.

Returns -1 If the message is too long (mlen > 245). Returns -2 If the seed is too short (slen < 253 - mlen). Returns 0 On success.

@remark The key * pk - should be initialized with * ocrypto_rsa2048_init_pub_key - . @remark The * seed - should consist of non-zero random bytes. @remark * c - may be same as * m - .
