RSA with User Chosen and Changeable Password

This research creates flexibility into the RSA and the split-private-key RSA cryptography. In the split-private-key RSA, the user can select, at his/her discretion, a password to derive the first of two private key portions. This paper provides an extension that further allows the user to change the password without resorting to a regeneration of the public/private key pair. Furthermore, validation of password input uses neither a hash value of the password nor other derivatives derived from just the password. Cryptosystems created accordingly strengthen password protection.
