As I understand this process is done in the client device for generating a unique key per transaction:
–> inject generated IPEK to client device
–> generate set of future keys (actually 21 future key) using IPEK+KSN … Continue reading some question about DUKPT process
What are the possible ways of reversing a key diversification algorithm? This is used to generate a different key for each user.
I know the operands involved (three 4 bytes values) and the result (the key, also 4 bytes long)… Continue reading Reverse a key diversification algorithm
It’s generally recommend to use a unique password for each online service, a random password generator to create them and a password manager to store them.
I’ve started to replace all my online passwords with this technique… Continue reading What’s the best length for randomly generated passwords? (Security vs. compatibility)

I’m in the process of obtaining a code signing certificate from a CA that requires the use of a smart card for the generation of the PKI key pair.
However, I would like to be in the possession of the private key, and not depe… Continue reading When generating PKI key pair with a smart card, who decides if the key is exportable?

I’m creating a python script that generates SSH keys for my raspberry pi SD card installation before I boot the SD for the first time, so I can get the fingerprints without having to boot it for the first time for it to gener… Continue reading Generating debian SSH keys with Python (paramiko library)
Our application is based on Java and Tomcat server. Which type of keystore is better ? does JKS or PCKS12 ? I understand JDK keytool by default creates JSK type then for which uses-cases one should go for PKCS12 type ?
I tr… Continue reading Which keystore type is good for java / Tomcat based applications
