<div class="description">Implementation of the String-to-key specifier (RFC4880 3.7)<br/>
<br/>
String-to-key (S2K) specifiers are used to convert passphrase strings
into symmetric-key encryption/decryption keys. They are used in two
places, currently: to encrypt the secret part of private keys in the
private keyring, and to convert passphrases to encryption keys for
symmetrically encrypted messages.</div>
