In fact, normally when I run the FLAC encoder, I run it with the "verify" option, which runs a decoder in parallel with the encoding process to prove that, indeed, bits out = bits in. The FLAC tester proves (beyond reasonalbe doubt) that bits out at a later date still = bits in when it was encoded by making an MD5 hash of the unencoded audio as it is being encoded. When FLAC test is run at a later date, the audio is decoded, another MD5 hash is created and compared with the hash generated when it was originally encoded. This proves, among other things, version compatibility if it was encoded with one version but decoded with another.
