1024-bit RSA Functions.

This group of functions is used for 1024-bit RSA. / /@{*/ / 1024 bit RSA PKCS1 V1.5 encryption.

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

• c - The generated 128-byte ciphertext.
• m - The message to be encrypted.
• m_len - Length of * m - . 0 <= m_len <= 117.
• seed - The random seed to be used for the padding.
• s_len - Length of * seed - . * s_len - >= 125 - * m_len -
• pk - A valid 1024-bit RSA public key.

Returns -1 If the message is too long (m_len > 117). Returns -2 If the seed is too short (s_len < 125 - m_len). Returns 0 On success.

@remark The key * pk - should be initialized with * ocrypto_rsa1024_init_pub_key - . @remark The * seed - should consist of non-zero random bytes. @remark * c - may be same as * m - .
