* On servers are stored checksums instead of passwords. Because it is almost impossible to recover your passwords. But it is possible to generate several passwords that will match the same checksum.

* Algorithms in which it is more important to detect changes in files than encryption are used to detect changes in the system. Sample programs for check file integrity Tripwire, AIDE.

=Understanding GPG keys=

* They can be used to encrypt messages in asynchronous encryption. In theory, a thief can steal the key message and steal private and will not be able to decrypt the message. Therefore, this method is considered the most secure method.

* Keys are used to sign the files, but does not give it a high level of safety. Because you can copy, edit the key from file.
