Expand description
2048-bit RSA PKCS1 V1.5 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.mlen
- Length of *m
- .c
- The 256-byte ciphertext to decrypt.sk
- A valid 2048-bit RSA secret key.
Returns -1 If decryption failed. Returns -2 If the output buffer is too short (mlen < length of message). Returns n If a message of length n was successfully decrypted.
@remark The key * sk
- should be initialized with * ocrypto_rsa2048_init_key
- .
@remark * m
- may be same as * c
- .
