HTACCESS Password Generator

What the HTACCESS Password Generator Does

This tool generates a single line for an Apache .htpasswd file — the credential store behind HTTP Basic Authentication. It takes a username and password and outputs the line in the {SHA} format that Apache understands, so you can drop it straight into your password file.

It is the quick way to add or update a Basic Auth user without running the htpasswd command-line tool, handy when you just need a line to paste into a server config.

How It Works

The password is hashed with SHA-1 using the browser's cryptography, and the raw digest is Base64-encoded. The tool then assembles the line as the username, a colon, the marker {SHA}, and that Base64 digest — the exact format Apache reads for this scheme.

When a visitor logs in, Apache hashes the password they enter the same way and compares it to the stored value. The catch is that the {SHA} scheme uses a plain, unsalted SHA-1: there is no per-password salt and no slowness, which is why it is considered weak today.

Generation algorithm

1. Take username and password. Read the username and the password you want to store.
2. Hash the password. Compute the SHA-1 digest of the password using the browser's cryptography.
3. Base64-encode the digest. Encode the raw SHA-1 bytes as Base64.
4. Assemble the line. Output username, a colon, the {SHA} marker and the Base64 digest, ready to paste.

What it outputs

The {SHA} scheme is an unsalted SHA-1. It is supported for legacy compatibility but is weak — for new setups, bcrypt (htpasswd -B) is the recommended, salted and slow alternative.

Privacy

Your username and password are processed entirely on your device, with no network request, so nothing is uploaded.

Because the hashing is local, the password is not transmitted while you generate the line. Still, store the resulting file securely and serve the protected area over HTTPS, since Basic Auth sends credentials with each request.

Nothing persists between sessions — close the tab and the inputs and output are gone.

Standards & references

• HTTP Basic Authentication — A simple authentication scheme where the server checks a username and password against a credential file. Apache reads these from a .htpasswd file referenced by a .htaccess or server config.
• The {SHA} scheme — An entry of {SHA} followed by the Base64 of an unsalted SHA-1 digest. Apache supports it, but the lack of a salt makes it vulnerable to dictionary and rainbow-table attacks — it exists mainly for legacy compatibility.
• bcrypt is recommended — For new Basic Auth setups, Apache and OWASP recommend bcrypt (htpasswd -B): it adds a salt and an adjustable cost factor that make password guessing expensive.

Accuracy & Limitations

The line is in the correct {SHA} format that Apache reads, so it works for HTTP Basic Auth as-is. For getting a user into a password file quickly, it does exactly what is needed.

The security is the weak point. The {SHA} scheme is an unsalted SHA-1: every instance of the same password produces the same digest, which makes it vulnerable to precomputed dictionary and rainbow-table attacks. It is supported for compatibility, not because it is strong.

There is no salt and no slowness, the two properties that make password hashes hard to crack. A modern setup should use bcrypt instead, which this tool does not produce — for that, the htpasswd command with the bcrypt option is the route.

Basic Auth itself sends the username and password with every request, encoded but not encrypted. Always serve a Basic-Auth-protected area over HTTPS so those credentials are not exposed on the network.

Real-World Use Cases

When to use it — and when not to

For a strong entry, generate a bcrypt line with the htpasswd command (the -B option) or a bcrypt-capable tool — it is salted and slow. Always put HTTPS in front of a Basic-Auth-protected area, whatever the hash.
