size_t fr_base64_encode	(	char *	out,
		size_t	outlen,
		uint8_t const *	in,
		size_t	inlen
	)

Base 64 encode binary data.

Base64 encode IN array of size INLEN into OUT array of size OUTLEN.

Parameters

[out]	out	Where to write Base64 string.
[in]	outlen	size of buffer including NULL byte.
[in]	in	Data to encode.
[in]	inlen	Length of data to encode.

Returns

• Amount of data we wrote to the buffer.
• -1 if output buffer was too small.

bool fr_is_base64

(

char

c

)

Check if char is in Base64 alphabet.

Note that '=' is padding and not considered to be part of the alphabet.

Parameters

c	char to check.

Returns

• true if c is a character from the Base64 alphabet.
• false if character is not in the Base64 alphabet.
