class rsa

// fields

ap_uint <L> exponent
ap_uint <N> modulus
ap_uint <N> rMod

void updateKey (
    ap_uint <N> inputModulus,
    ap_uint <L> inputExponent
    )

Update key before use it to encrypt message.

Parameters:

inputModulus	Modulus in RSA public key.
inputExponent	Exponent in RSA public key or private key.

void updateKey (
    ap_uint <N> inputModulus,
    ap_uint <L> inputExponent,
    ap_uint <N> inputRMod
    )

Update key before use it to encrypt message.

Parameters:

inputModulus	Modulus in RSA public key.
inputExponent	Exponent in RSA public key or private key.
inputRMod	2^(2 * N) mod modulus, pre-calculated by user

void process (
    ap_uint <N> message,
    ap_uint <N>& result
    )

Encrypt message and get result. It does not include any padding scheme.

Parameters:

message	Message to be encrypted/decrypted
result	Generated encrypted/decrypted result.
