Faster and easier than ever in a server
SeSeLe is a command-line wizard to create and manage X.509 certificates in two ways: Self-signed certificates + Certification Authority, and Let’s Encrypt certificates.
Letsencrypt management is intended to call ACME-client for certificates renewal and files redistribution to unprivileged hosts (those that can’t attend TCP/443 port).
Generated certificates are useful for most TLS secured services such as HTTPs, IMAPs, POP3s, SMTPs, etc.
For self-signed files, the only thing you will need to remember are passphrases.
