I get the public key from the 3rd party client. I import the key into my environment. I code my JCL to use // KEYLABL1=?MyEKMServerJCEKS?, // KEYENCD1=L, // KEYLABL2=?CompanyXPublicKeyJCEKS?, // KEYENCD2=H, Where my public key is called MyEKMServerJCEKS and the 3rd party's public key is called CompayXPublicKeyJCEKS that I had imported into my system. My system is setup to use the JCERACFKS keystore for encryption with E05 Tape Drives in a TS3500. The KEYENCD2=H is where the HASH is handled? Lizette > >>I have not worked with this yet.
