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

| ) |
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. If that length cannot be represented, then no data is written to the buffer and *olen is set to the maximum length representable as a size_t.
- Note:
- Call this function with dlen = 0 to obtain the required buffer size in *olen
