I have created a keystore using keytool.
I have tried managing a keystore through the API and was able to generate key pairs and store them. (using setCertificateEntry(), setKeyEntry() etc.) However, I cannot retrive them with getKey().
Calling the method throws the exception
"java.security.UnrecoverableKeyException: DER input, Integer tag
error".
Someone knows how to interpret this error?

It could be that KeyStore is assuming you try to retrieve a private key.
So when it faces a public key, things go wrong because the expected key (a private key) specified by it Distinguished Encoding Rules(DER) encoding is incorrect.

Hi, I ran in to this problem awhile back and found a fix for it. My post regarding it is here:
