Editing UUHash (section)

=== Test Vectors ===

Given below are hashes (base64 and hex) for strings of various lengths containing only <code>0x00</code> or <code>0xFF</code> bytes, generated by sig2dat.

Note ''here'' that all strings that have a complete MD5 chunk have the same 128-bit prefix because their first chunks are the same (either 0x00 or 0xFF). For files that have the same number of chunks the CRC part differs only because of the included file length (all chunks are identical, or this weren't the case). For files up to 300 KiB, the file length can be extracted from the last four bytes of the hash; ''smallhash'' is ~0.
