Expand description
1024-bit RSA OAEP SHA256 decryption with CRT acceleration.
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 with CRT coefficients.
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_crt_key
- .
@remark * m
- may be same as * c
- .
