Cryptography
Description
Cryptography can be used to ensure the confidentiality, integrity and authenticity of information, either at rest or in transit. Common uses of cryptography on computer systems are to encrypt:
- individual files (for example using GPG or one of the successors to the original UNIX
cryptcommand); - complete filesystems (for example using dm-crypt or Truecrypt);
- network connections (for example using SSL/TLS to protect HTTP web page transfers); and
- passwords (for example in a shadow password file, or as part of a single sign-on authentication system such as Kerberos).
