[BUG] Couldn't generate Proxyman Certificate due to long name

Description

Thanks to Pierre to help me to get the error log when he couldn't generate the certificate on his machine.

Generating RSA private key, 2048 bit long modulus

After investigating, it turns out that the CommonName must be lesser than 64 char. Proxyman would get the computer name and put it as a part of the Common Name. Thus, in some cases, the name is long and result in the OpenSSL error.

After he shortens the name, it works as expected 👍

Acceptance Criteria

• Reproduce and trim the text if it's too long
• Double-check if the name is non-ASCII char
