Function Documentation

u_int dpl_base64_decode	(	const u_char *	in_buf,
		u_int	in_len,
		u_char *	out_buf
	)

decode a base64-encoded buffer to the original binary data.

Parameters

in_buf	input buffer to decode
in_len	input buffer size
out_buf	base64 output buffer (must be at least of size DPL_BASE64_ORIG_LENGTH(in_len))

Returns

out_len length of decoded output

Parameters

in_buf	input buffer to encode
in_len	input buffer size
out_buf	base64 output buffer that must be at least of size DPL_BASE64_LENGTH(in_len)

Returns

out_len length of base64 output
