<x id="START_H2" />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" />

<x id="START_PARAGRAPH" />If you're like most people, you reuse the same password in many different places.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />Unfortunately evil people know that. Once hackers break into just one insecure website, they steal passwords, and (knowing that most people reuse their passwords) they use it to log in other places. When they get in to all your accounts, it gets ugly.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />But who can really remember a different password for every website? That's where hashapass comes in.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />Hashapass lets you remember just one password, and use it to generate a different password for every website or service.<x id="END_PARAGRAPH" />

It could be a password that you already use, or a new one -- or even a long pass phrase -- but do make sure that you remember it.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />To generate new passwords, choose an easy-to-remember parameter, like the name of the website that you're creating a password for. Hashapass will then generate a password based on your master password and the parameter. <x id="START_EMPHASIS" />The passwords are never transmitted to our server<x id="END_EMPHASIS" />.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />When you need that password again, just enter the same master password and parameter.
