Macro Definition Documentation

◆ POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL

#define POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL -0x0010

Output buffer too small.

Referenced by base64_decode().

◆ POLARSSL_ERR_BASE64_INVALID_CHARACTER

#define POLARSSL_ERR_BASE64_INVALID_CHARACTER -0x0012

Invalid character in input.

Function Documentation

◆ base64_decode()

int base64_decode	(	unsigned char *	dst,
		size_t *	dlen,
		const unsigned char *	src,
		size_t	slen )

Decode a base64-formatted buffer.

Parameters

dst	destination buffer
dlen	size of the buffer
src	source buffer
slen	amount of data to be decoded

Returns: 0 if successful, POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL, or POLARSSL_ERR_BASE64_INVALID_DATA if the input data is not correct. *dlen is always updated to reflect the amount of data that has (or would have) been written.

Note: Call this function with *dlen = 0 to obtain the required buffer size in *dlen
