Expand description

1024 bit RSA OAEP SHA256 decryption.

The ciphertext * c - is decrypted to the message returned in * m - .

m - The decrypted message. The buffer must be long enough to hold the message.
m_len - Length of * m - .
c - The 128 byte ciphertext to decrypt.
label - The label associated with the message.
l_len - Length of * label - . May be 0.
sk - A valid 1024 bit RSA secret key.

Returns -1 If decryption failed. Returns -2 If the output buffer is too short (m_len < length of message). Returns n If a message of length n was successfully decrypted.

@remark The key * sk - should be initialized with * ocrypto_rsa1024_init_key - . @remark * m - may be same as * c - .
