A computer implemented method provides access to processes and data using strengthened password. During an initialization phase, an access code is stored in a memory of a computer system. The access code is an application of a one-way hash function to a concatenation of a password and a password supplement. The size of the password supplement is a fixed number of bits. During operation of the system, a user enters a password, and the one-way hash function is applied to concatenations of the password and possible values having the size of the password supplement to yield trial access codes. Access is granted when one of the trial access codes is identical to the stored access code.

[ We claim:] [26.] A computer program product for use in conjunction with a computer system, the computer program product comprising a computer readable storage medium and a computer program mechanism embedded therein, the computer program mechanism comprising:a first module for establishing a password, including instructions for:combining a first password with a supplement to generate a full password, wherein the size the supplement is a fixed number of bits; andapplying a one-way hash function to the full password to generate an access code stored in a memory of a computer system; anda resource access module, including instructions for:combining a second password with possible supplements to generate trial full passwords, each possible supplement being the fixed number of bits;applying the one-way hash function to the trial full passwords to generate trial access codes; andallowing access to the resource if one of the trial access codes is identical to the stored access code;whereinthe first module includes instructions for concatenating the first password and supplement to generate the full password; andthe resource access module includes instructions for concatenating the second password and the possible supplements to generate the trial full passwords.
