We are using Pkcs11Interop library for cryptography and we customize&implement Pkcs11Interop code samples for our project where Pkcs11Interop documents in Github. In production, not everyday but we have to restart server after CPU usage reach maximum when we get a consecutive(4 or 5 times) CKR_ENCRYPTED_DATA_INVALID exception. What cause this ? How can we fix this problem ? Any ideas will be appreciated. If anyone want I can share our code sample. Thanks for helping.
