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?
