Function Documentation

int R_CR_asym_decrypt ( R_CR * crypto,

unsigned char * data,

unsigned int dlen,

unsigned char * out,

unsigned int * olen

) ;

Decrypts a block of data with an asymmetric key.
Parameters:

crypto [In] A pointer to the cryptographic object.
Must be allocated the correct type and initialized by calls to R_CR_new() and R_CR_asym_decrypt_init() respectively.

data [In] A pointer to the data to decrypt.
If NULL is passed, the required size of the buffer is returned.

dlen [In] The number of Bytes to decrypt.

out [Out] The buffer that takes the decrypted data.
Must be of sufficient length to contain the encrypted data.

olen [In, Out] The length of the decrypted data, in out.

Returns:
R_ERROR_NONE indicates success.
See Error Identifiers for valid values.

R_CR_asym_decrypt_init().

int R_CR_asym_decrypt_init ( R_CR * crypto,

R_PKEY * key

) ;

Initializes an asymmetric key decryption operation.
Parameters:

crypto [In] A pointer to the cryptographic object.
Must be allocated the correct type via R_CR_new().

key [In] The key to use.

Returns:
R_ERROR_NONE indicates success.
See Error Identifiers for valid values.
