Caution!<x id="END_SPAN" />
Most systems will keep a history of recently-typed commands. You probably do not want to use the above template directly, but rather inside of a shell script that will prompt you for your master password.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />
Simon Elmir contributed just such a script:<x id="END_PARAGRAPH" />

About Hashapass<x id="END_H2" /><x id="START_PARAGRAPH" />
Hashapass is a password generator which uses a mathematic formula to create new passwords based on a "master" password and a parameter.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />
The formula is calculated in the safety of your web browser, without any information being transmitted over the Internet.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />
The generated password is computed as the first 8 characters of the Base64 encoding of HMAC-SHA1(master password, parameter). HMAC-SHA1 is defined on byte arrays, so only the lowest-significant byte of the Unicode code point for each character of the master password and parameter is used in the calculation of the HMAC-SHA1.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />
There's no secret to this formula:<x id="START_LINK_1" />
SHA1<x id="END_LINK" />
,<x id="START_LINK_2" />
HMAC<x id="END_LINK" />
and<x id="START_LINK_3" />
Base64<x id="END_LINK" />
are all well-known algorithms, which guarantees that other people can implement products that are compatible with Hashapass.<x id="END_PARAGRAPH" />
