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
...............................................................................................................+++++..+++++
e is 65537 (0x10001)\nproblems making Certificate Request
4702391744:error:0DFFF097:asn1 encoding routines:CRYPTO_internal:string too long:asn1/a_mbstr.c:156:maxsize=64\n"))

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
