Getting error - java.security.InvalidKeyException: Private Key cannot be used to encrypt.

I am getting below error while I try to encrypt using RSA key on HPUX platform

java.security.InvalidKeyException: Private Key cannot be used to encrypt.

I didn't face any issue on Linux and Windows with Oracle JDK installed. Can anybody please suggest workaround for this issue. Code is legacy and I can't change existing functionality.

"try to encrypt" what, _how_, exactly? As usual, showing actual
commands (or program statements) with their actual output can be more
helpful than vague descriptions ("try to encrypt") or interpretations.

uname -a

Java version?

I know nothing, but that message suggests (to me) that you've
specified a private key where you should have specified a public key.

I can't see what you did on those systems, either.

Knowing nothing, I might try a Web search for, say:

"java.security.InvalidKeyException: Private Key cannot be used to encrypt."
