Macro Definition Documentation

◆ BASE64_DEC_SIZE

#define BASE64_DEC_SIZE ( __enc_size__ ) (((__enc_size__) / 4) * 3)

Provides an estimate of how much raw data results from decoding of enc_size many base-64 encoded bytes. Unlike the macro above, this macro may slightly (by up to 2 bytes) overestimate the actual size of the decoded data, so be sure to always check the return value of base64_decode to avoid accessing uninitialized data.

Definition at line 41 of file base64.h.

◆ BASE64_ENC_SIZE

#define BASE64_ENC_SIZE ( __raw_size__ ) ((((__raw_size__) + 2) / 3) * 4)

Provides a precise computation of how much base64 data will be generated when raw_size many binary bytes a base64-encoded.

Function Documentation

◆ lacf_base64_decode()

ssize_t lacf_base64_decode	(	const uint8_t *	encoded,
		size_t	encoded_size,
		uint8_t *	raw
	)

Front-end to base64_decode2 with mod set to zero.

Definition at line 182 of file base64.c.

◆ lacf_base64_decode2()

ssize_t lacf_base64_decode2	(	const uint8_t *	encoded,
		size_t	encoded_size,
		uint8_t *	raw,
		int	mod
	)

Decodes a Base64 encoded string, previously encoded with base64_encode.

Parameters

encoded	The encoded Base64 bytes.
encoded_size	Number of bytes in ‘encoded’.
raw	Output buffer to be filled with decoded bytes. This buffer must contain at least BASE64_DEC_SIZE(encoded_size) bytes.

Returns: The number of actual message that were encoded in the Base64 buffer, or -1 if the input was malformed.

◆ lacf_base64_encode()

size_t lacf_base64_encode	(	const uint8_t *	raw,
		size_t	raw_size,
		uint8_t *	encoded
	)

Front-end to base64_encode2 with mod set to zero.

Definition at line 93 of file base64.c.

◆ lacf_base64_encode2()

size_t lacf_base64_encode2	(	const uint8_t *	raw,
		size_t	raw_size,
		uint8_t *	encoded,
		int	mod
	)

Encodes a string of bytes into a Base64 encoding.
