Key pair generation

Abstract

A method for generating a private key for an asymmetric key cryptography algorithm using a password, wherein the password can be changed without the private key changing is presented. The method has applications to blockchain wallets, digital signing, passkeys, and other identity and access management systems in which password changing is currently difficult or impossible. The method generates a first matching code for a first password to derive a private key, and when the first password is changed to be a second password, the first matching code is altered to a second matching code to maintain derivation of the same private key, and the first password may be discarded or forgotten.
