What are MD5, SHA1 and CRC?

How do I check them?

Thanks.

CRC=Cyclical Redundancy Checking
MD5=Message Digest 5
SHA1=Secure Hash Algorithm 1

They are usually used to check the integrity of a file compared to a given expected value. To use them, you need the file in question, the associated .md5 or .sha1 file (contains the expected value, you can open it in plain text if curious) and a check software. The check softwares can be found simply by googling "sha1 check" and "md5 check"; I cannot really recommend any good GUI-based utility as I use only the command line ones.

Some hex editors like HxD also have the ability to compute these checksums and compare them to an expected result.
