SmartCardCryptoProvider::decrypt()

Decrypt data in a single part.

Synopsis:

#include <smartcard_spi/SmartCardCryptoProvider.hpp>

virtual sc_response_code_t smartcard_spi::SmartCardCryptoProvider::decrypt(const unsigned char *ciphertext, unsigned int ciphertextLength, unsigned char *plaintext, unsigned int &plaintextLength)

Since:

BlackBerry 10.3.0

Arguments:

ciphertext: The input buffer containing the ciphertext to be decrypted; must not be NULL.

ciphertextLength: The ciphertext buffer length.

plaintext: The output buffer where the plaintext data will be written. If NULL, only the plaintext length will be returned.

plaintextLength: On input, this parameter specifies the plaintext buffer length. On output, this parameter specifies the plaintext length.

Library:

libscs (For the qcc command, use the -l scs option to link against this library)

Description:

This function decrypts encrypted data in a single part.

Algorithm specific notes:

RSA: No padding bytes are added or removed.

Depending on card driver implementation, this function may or may not be called multiple times without re-initializing.

Returns:

If the function succeeds, SC_SCARD_S_SUCCESS is returned. Otherwise, an error code is returned.
