Unmatched gcm tag - wrong key
WebJan 7, 2024 · 145 5. Normally, signing is done asymmetrically (i.e. the signer uses his private key to sign the data, then the verifier uses the signers public key to verify the signature). AES-GCM is symmetric encryption (the same key is used to encrypt and decrypt). So, I'm struggling with the idea of using symmetric encryption for signing. WebOct 22, 2024 · Start titles only

Currently I am using EBC to encrypt the IV, as otherwhise I would need another IV to encrypt the previous IV and so on. The problem is that I am able to decrypt the cipher using a a completely different key from the enryption.
