Expand description

RSA primitives.

This group of functions is used for basic RSA arithmetic. / /@{*/ / RSA public key exponentiation. c = m^e mod n

c - The generated ciphertext.
c_len - Length of * c - .
m - The message to be encrypted.
m_len - Length of * m - .
pk - A valid RSA public key.
mem - The working memory. Length OCRYPTO_RSA_PUB_MEM_SIZE(bits).

Returns -1 If the input is too large (m >= n). Returns 0 On success.

@remark The key * pk - should be initialized with * ocrypto_rsa_init_pub_key - . @remark * c - , * m - , and * mem - may be same.
