Detailed Description

headers of Base64 encode and decode functions

Function Documentation

int b64decode	(	const char *	in,
		size_t	l,
		string *	out
	)

decode base64 string to plain text

Parameters

in	base64 text
l	length of in
out	string to store decoded string (memory will be malloced)

Return values

<0	negative error code
0	on success
1	on parse error

The contents of out are undefined as long as something else than 0 is returned, i.e. the memory is freed but the freed pointer may still be recorded in out.

A final 0-byte will always be added to out->s, which is not counted in out->len.

int b64encode	(	const string *	in,
		string *	out,
		const unsigned int	wraplimit
	)

encode plain text string to Base64

Parameters

in	plain text string
out	string to store Base64 string (memory will be malloced)
wraplimit	the number of characters after which a CRLF pair should be inserted

Return values

0	on success
<0	negative error code
