SHA-1 and MD5
A while ago I installed HashTab (HashTab... is the coolest thing ever! - adds a tab "File Hashes" that then works out the CRC, MD5 and SHA-1 of the file), and have used it alot to compare files to make sure they are identical etc.
My question is - as I understand it, CRC -> MD5 -> SHA are more and more comprehensive in terms of hashing, and length etc (remember reading ages ago someone spoofed an MD5 hash or something). So the question is, if the SHA-1s matched on two files, then is it DEFINITE that the MD5s will also match up? I.e. I can just use the SHA-1 and not also need to check the MD5 or CRC.
