Function Documentation

from64tobits()

int from64tobits	(	char *	out,
		const char *	in
	)

Convert base64 to bytes array.

Parameters

out	output buffer in bytes. The buffer size must be at least (3 * size_of_in_buffer / 4) bytes long.
in	input base64 buffer
inlen	base64 buffer length

Returns

0 on success, -1 on failure.

Definition at line 114 of file base64.c.

from64tobits_fast()

int from64tobits_fast	(	char *	out,
		const char *	in,
		int	inlen
	)

Definition at line 122 of file base64.c.

from64tobits_fast_with_bug()

int from64tobits_fast_with_bug	(	char *	out,
		const char *	in,
		int	inlen
	)

Definition at line 199 of file base64.c.

to64frombits()

int to64frombits	(	unsigned char *	out,
		const unsigned char *	in,
		int	inlen
	)

Definition at line 77 of file base64.c.

to64frombits_s()

int to64frombits_s	(	unsigned char *	out,
		const unsigned char *	in,
		int	inlen,
		size_t	outlen
	)

Convert bytes array to base64.

Parameters

out	output buffer in base64. The buffer size must be at least (4 * inlen / 3 + 4) bytes long.
in	input binary buffer
inlen	number of bytes to convert

Returns

0 on success, -1 on failure.
