Macro Definition Documentation

Output buffer too small.
#define POLARSSL_ERR_BASE64_INVALID_CHARACTER -0x0012
Invalid character in input.
Function Documentation
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
