Expand description
2048-bit RSA OAEP SHA256 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 <= 190.label
- The label associated with the message.llen
- Length of *label
- . May be 0.seed
- 32-byte random seed.pk
- A valid 2048-bit RSA public key.
Returns -1 If the message is too long (mlen > 190). Returns 0 On success.
@remark The key * pk
- should be initialized with * ocrypto_rsa2048_init_pub_key
- .
@remark * c
- may be same as * m
- .
