Function Documentation

◆ osmo_base64_decode()

int osmo_base64_decode	(	unsigned char *	dst,
		size_t	dlen,
		size_t *	olen,
		const unsigned char *	src,
		size_t	slen
	)

Decode a base64-formatted buffer.

Parameters

dst	destination buffer (can be NULL for checking size)
dlen	size of the destination buffer
olen	number of bytes written
src	source buffer
slen	amount of data to be decoded

Returns: 0 if successful, MBEDTLS_ERR_BASE64_BUFFER_TOO_SMALL, or MBEDTLS_ERR_BASE64_INVALID_CHARACTER if the input data is not correct. *olen is always updated to reflect the amount of data that has (or would have) been written.

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

◆ osmo_base64_encode()

int osmo_base64_encode	(	unsigned char *	dst,
		size_t	dlen,
		size_t *	olen,
		const unsigned char *	src,
		size_t	slen
	)

Encode a buffer into base64 format.

Parameters

dst	destination buffer
dlen	size of the destination buffer
olen	number of bytes written
src	source buffer
slen	amount of data to be encoded

Returns: 0 if successful, or MBEDTLS_ERR_BASE64_BUFFER_TOO_SMALL. *olen 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 *olen
