SmimeUtil configurable signature algorithm about simple-java-mail HOT 2 CLOSED

Hhm, it's a bit difficult to trace back, but it seems the key is empty from the moment it is attempted to be obtained from the PKCS12 store. Is it possible you used the wrong name as key alias? I noticed Simple Java Mail doesn't do a null-check there, so that's something to be improved.

You are right. The reason was the alias. However, it wasn't wrong by me, it looks like I have received it by Geant wrong or missing. Printin the information with keytool told that the alias is "1", but that wasn't working. So, I have changed the alias with keytool -changealias -alias "1" -destalias "new-alias" -keystore /path/to/keystore and now it works.

Thanks so much. I have tested for days and contacted our responsible department until you wrote, The weird thing is, I tried it before renaming the alias, but it wasn't worked. I think my fault was, that I haven't shutdown the instance correctly before deploying the new one and so it probably used an old state.
