acme.sh: Issue a certificate using standalone TLS mode using port 443.
$ acme.sh --issue --alpn --domain ${example-com}
try on your machine
The command acme.sh --issue --alpn --domain ${example-com} is used to request a SSL/TLS certificate from Let's Encrypt using the acme.sh client.
Here's a breakdown of the command:
- acme.sh: Refers to the acme.sh script, which is a lightweight ACME client for obtaining certificates from Let's Encrypt.
- --issue: Specifies that you want to request a certificate.
- --alpn: Indicates that you want to use the Application-Layer Protocol Negotiation (ALPN) method for domain validation. ALPN is a protocol extension used during the SSL/TLS handshake to negotiate the protocol to be used (such as HTTP/1.1 or HTTP/2).
- --domain ${example-com}: Specifies the domain for which you want to obtain the certificate. The ${example-com} is just a placeholder, and you would replace it with the actual domain name.
Overall, this command is requesting a certificate for the specified domain using the ALPN method for domain validation.
