We are in the process of building encryption/decryption applications. We are using the IBM QC3ENCDT AND QC3DECDT API'S. I've starting testing against our database using apprx 3000 records to encrypt and then decrypt. Out of that 3000 records, there are 17 instances of failure to decrypt to clear data and it is always the same 17 records in this group. We are at release V5R3. Has anyone had experience using these api's with this type of failure? If not, I'll look to the programming. Thanks in advance.
