Detailed Description

Function Documentation

openssl_aes256_file_decrypt()

bool openssl_aes256_file_decrypt	(	const wickr_cipher_key_t *	key,
		const char *	sourceFilePath,
		const char *	destinationFilePath,
		bool	only_auth_ciphers
	)

Decrypt a file to another file

Utilizes a small amount of stack memory to decrypt a large file. This function is byte-format compatible with standard memory-based AES functions from this library.

Parameters

key	the cipher key to use for the decryption operation
sourceFilePath	the path to the source file to decrypt
destinationFilePath	the location to save the decrypted file
only_auth_ciphers	if true, only authenticated ciphers may be used for decryption

Returns

true if the decryption succeeds, false if the sourceFilePath, or destinationFilePath is inaccessible, or the incorrect key is presented

openssl_aes256_file_encrypt()

bool openssl_aes256_file_encrypt	(	const wickr_cipher_key_t *	key,
		const char *	sourceFilePath,
		const char *	destinationFilePath
	)

Encrypt a file to another file

Utilizes a small amount of stack memory to encrypt a large file. This function is byte-format compatible with standard memory-based AES functions from this library.

Parameters

key	the cipher key to use for the encryption operation
sourceFilePath	the path to the source file to encrypt
destinationFilePath	the location to save the encrypted file

Returns

true if the encryption succeeds, false if the sourceFilePath, or destinationFilePath is inaccessible, or the encryption operation fails.
