Abstract: Techniques for managing certificates on a computing device are provided. An example method according to these techniques includes receiving an image file comprising a hash value of a certificate on which a certificate action is to be performed, the certificate action being a revocation action or an activation action, the image file having been signed by a signing certificate, determining whether the image file has been signed by a valid certificate by comparing a hash value of the signing certificate to a plurality of hash values associated with certificates stored in a one-time programmable memory of the computing device, and performing the certificate action, responsive to the image file having been signed by the valid certificate and the certificate on which the certificate action is to be performed having been found in the memory, by setting a value of an indicator associated with the certificate in the memory.

Abstract: Systems and methods for providing accelerated passphrase verification are disclosed. In one embodiment, a method includes receiving a full security string, generating a full security string hash code, storing the full security string hash code in a memory, determining at least one substring based on an entropy value associated with one or more leading characters in the full security string, generating at least one substring hash code and at least one corresponding character count value, such that the corresponding character count value equals a number of characters in the at least one substring, and storing the at least one substring hash code and the at least one corresponding character count value in the memory.
