I am working on a cryptographic based symmetric algorithm. But before that’s, I have to make software code in java for a previous proposed algorithm. The algorithm that’s i have to solve looks like:
A. Encryption Process

I have a server that needs to sign JWTs asymmetrically. I can either generate a new public/private keypair or re-use my keypair used for my server certificate. Is there any concern about re-using my server’s certificate? That… Continue reading Signing JWTs with server’s SSL/TLS certificate
I understand that it is possible to combine symmetric and asymmetric encryption in a way that makes use of the performance of symmetric encryption, and also getting the benefits of being able to separate the knowledge needed … Continue reading How to combine symmetric and asymmetric encryption to encrypt large files?
I want to sign webhooks from my web service with a JSON Web Signature (part of JWT standard), ideally using asymmetric keys (so, using RSA or elliptic curve cryptography).
What is the recommended or standard way to publish m… Continue reading Signing webhooks with asymmetric keys
I’m passing sensitive financial data to a payment processor online via cloud functions and would like your expert opinions, please.
The workflow is as follows:
A customer indicates they want to transact by tapping a check… Continue reading Is this strategy end 2 end encryption and secure?
Assuming that I have a way to associate a combination of public private key encryption with real people/user. The private key is stored on the device of the user.
User have to communicate with some web service on multiple ho… Continue reading Can Asymmetric encryption be used instead of modern authentication strategy?
I know that keys in a TPM key hierarchy are encrypted with their parent keys. But I read that those parent keys (for instance an asymmetric SRK) need to have some symmetric secret for said encryption. Is is mandatory to encry… Continue reading Asymmetric/Symmetric Encryption of a TPM key hierarchy
I was wondering about whether there exists a scheme that would have the following properties:
Be asymmetric (Encrypt with public key, decrypt with private key)
Be secure by today’s standards (as hard as RSA 2048)
Short publ… Continue reading Which scheme provides the shortest public key, while being secure? [on hold]
Bob is sending message X to Alice. He encrypts X with Alice’s public key using gpg and sends her encrypted message (ciphertext).
Later Alice claims that Bob made a mistake and the ciphertext was not created with her public key.
