fix: use random nonce per call in AES-GCM onboarding signature#480
Merged
Conversation
Replace static IV derived from the key with crypto.randomBytes(12) generated fresh on every encryption call. New output format: hex(iv[12] || ciphertext || tag[16]) The receiver reads the first 24 hex chars as the IV before decrypting. Co-authored-by: ankitdas13 <ankit.das@razorpay.com>
Upgrade from v2 to v4 to fix cache backend compatibility. Co-authored-by: ankitdas13 <ankit.das@razorpay.com>
