What is htpasswd?
Htpasswd is a command tool for the open-source HTTP server Apache Httpd that generates password files for HTTP basic authentication.
What is the difference between encryption methods?
MD5:Use MD5 to encrypt passwords. On Windows, Netware, and TPF, this is the default encryption method.
Crypt:Use crypt () to encrypt passwords. This is the default on all platforms except Windows, Netware, and TPF. Although it is supported by htpasswd on all platforms, However, it is not supported by the HTTPD server on Windows, Netware, and TPF.
SHA:Use SHA to encrypt passwords. It is for easy migration to or from LDAP Directory Interchange Format. (Ldif) designed for Netscape.
Plain:Do not encrypt, use plain text passwords. Although htpasswd can create such passwords on all platforms, the htpd background is only on Windows, Plain text passwords are supported on Netware and TPF.
Why make it online?
If we don't use the Apache server, such as using nginx, etc., we may not be able to generate password files without this command-line tool at hand. With an online version, it is convenient for server administrators to use.
