openssl_private_encrypt($originalData, $encryptData, $privateKey, OPENSSL_ALGO_DSS1)Warning message:
Warning: openssl_private_encrypt(): key type not supported in this PHP build!
Key: *.pem
-----BEGIN DSA PRIVATE KEY-----

-----END DSA PRIVATE KEY-----It seems that this format of key is not supported for encryption. The content of this key is provided by the partner, and their development language is JAVA.
