  About Hashapass
  <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_H2" />Informaciones sobre Hashapass<x id="END_H2" /><x id="START_PARAGRAPH" />Hashapass es un generador de contraseñas que utiliza una fórmula matemática para crear nuevas contraseñas en base a una contraseña principal y un parámetro.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />La fórmula está calculada en la seguridad de tu navegador web, sin que ninguna información sea trasmitida en el Internet.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />La contraseña generada está calculada de la manera siguiente: se toman los 8 primeros caracteres de Base64(HMAC-SHA1(contraseña principal, parámetro)). HMAC-SHA1 está definido sobre tablas de bytes, entonces solamente los bytes de menos peso del punto de coda Unicode de cada carácter de la contraseña principal o del parámetro se toman en cuenta para calcular el HMAC-SHA1.<x id="END_PARAGRAPH" /><x id="START_PARAGRAPH" />No hay secreto en esta fórmula: <x id="START_LINK_1" />SHA1<x id="END_LINK" />, <x id="START_LINK_2" />HMAC<x id="END_LINK" /> y <x id="START_LINK_3" />Base64<x id="END_LINK" /> son todos algoritmos bien conocidos, lo que garantiza que otra gente puedan implementar fácilmente productos que sean compatibles con Hashapass.
