keys generated by openssl_private_encrypt using DSA algorithm cannot be encrypted

<code>openssl_private_encrypt($originalData, $encryptData, $privateKey, OPENSSL_ALGO_DSS1)</code>

Warning message:

<code>Warning: openssl_private_encrypt(): key type not supported in this PHP build!
</code>

Key: *.pem

<code>-----BEGIN DSA PRIVATE KEY-----
密钥内容
-----END DSA PRIVATE KEY-----</code>

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.

I use RSA formatted key contents and then encrypt using openssl_private_encrypt with no problem.
There is very little content related to PHP DSA encryption on the Internet, which is a headache.

Is privateKey pronounced correctly?
