Computer Keychains
By analogy to the physical object, the terms keychain and keyring are often used for software that stores cryptographic keys. The term keychain was first introduced in a series of IBM developerWorks articles. The term is used in GNU Privacy Guard to store known keys on a keyring.
Mac OS X uses a password storage system called Keychain.
A "keyring" is also the name of a password manager application working under the GNOME desktop manager (used for example in Ubuntu operating system). It is general term used in cryptography for a database of multiple keys or passwords.
