Member Function Documentation

encrypt()

int crypto::cipher::cbc_t::encrypt	(	const std::string_view &	plaintext,
		std::uint8_t *	cipher,
		aes_t *	iv )

Encrypts the plaintext using AES CBC mode. length of cipher must be at least: round_to_pkcs7_padded(plaintext.size())

Parameters

plaintext	The plaintext data to be encrypted.
cipher	The buffer where the resulting ciphertext will be written.
iv	The initialization vector to be used for the encryption.

Returns

The total length of the ciphertext written into cipher. Returns -1 in case of an error.

This function encrypts the given plaintext using the AES key in CBC mode. The initialization vector (IV) is also provided. The function handles the creation and initialization of the encryption context, and manages the encryption process. The resulting ciphertext is written into the cipher buffer.
