Function Documentation

crypto_pwbox()

int crypto_pwbox	(	uint8_t **	out,
		size_t *	outlen_out,
		const uint8_t *	input,
		size_t	input_len,
		const char *	secret,
		size_t	secret_len,
		unsigned	s2k_flags
	)

Make an authenticated passphrase-encrypted blob to encode the input_len bytes in input using the passphrase secret of secret_len bytes. Allocate a new chunk of memory to hold the encrypted data, and store a pointer to that memory in *out, and its size in outlen_out. Use s2k_flags as an argument to the passphrase-hashing function.

crypto_unpwbox()

int crypto_unpwbox	(	uint8_t **	out,
		size_t *	outlen_out,
		const uint8_t *	inp,
		size_t	input_len,
		const char *	secret,
		size_t	secret_len
	)

Try to decrypt the passphrase-encrypted blob of input_len bytes in input using the passphrase secret of secret_len bytes. On success, return 0 and allocate a new chunk of memory to hold the decrypted data, and store a pointer to that memory in *out, and its size in outlen_out. On failure, return UNPWBOX_BAD_SECRET if the passphrase might have been wrong, and UNPWBOX_CORRUPT if the object is definitely corrupt.
