Description

TBase64DecodingMode determines the decoding algorithm used by TBase64DecodingStream. There are 2 modes:

bdmStrict

Strict mode, which follows RFC3548 and rejects any characters outside of base64 alphabet. In this mode only up to two '=' characters are accepted at the end. It requires the input to have a Size being a multiple of 4, otherwise an EBase64DecodingException exception is raised.

bdmMime

MIME mode, which follows RFC2045 and ignores any characters outside of base64 alphabet. In this mode any '=' is seen as the end of string, it handles apparently truncated input streams gracefully.
