| 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 (can be NULL for checking size) 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_CHARACTER 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 *dst = NULL or *dlen = 0 to obtain the required buffer size in *dlen
| int base64_encode | ( | unsigned char * | dst, |
| size_t * | dlen, | ||
| const unsigned char * | src, | ||
| size_t | slen | ||
| ) |
Encode a buffer into base64 format.
- Parameters:
-
dst destination buffer dlen size of the buffer src source buffer slen amount of data to be encoded
- Returns:
- 0 if successful, or POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL. *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
