body: <p>Is it possible to decrypt(retain the actual string) the password which is saved in db using <code>SHA1</code> algorithm.</p>
  
  <p>Example:If password is <code>"password"</code> and it is stored in db as <code>"sha1$4fb4c$2bc693f8a86e2d87f757c382a32e3d50fc945b24"</code>,is any chance to retain the same <code>"password"(string)</code> from <code>"sha1$4fb4c$2bc693f8a86e2d87f757c382a32e3d50fc945b24"</code> </p>
