NAME

3proxy_crypt - utility to generate encrypted passwords for 3proxy

SYNOPSIS

3proxy_crypt password
3proxy_crypt salt password

DESCRIPTION

_ 3proxy_crypt _ is a utility to generate encrypted password hashes for use with 3proxy configuration. Encrypted passwords allow the system to avoid storing passwords in cleartext in configuration files.

When invoked with a single argument, it produces an NT password hash (MD4-based, suitable for NTLM authentication). The output is prefixed with NT:.

When invoked with two arguments (salt and password), it produces a BLAKE2b password hash. The salt length is limited to 64 characters. The output is prefixed with CR:.

The resulting hash can be used in the 3proxy configuration file with the users directive instead of a cleartext password.

OPTIONS

password

Cleartext password to encrypt.

| |

salt

| |

Salt string for BLAKE2b hashing (max 64 characters).

| |

EXAMPLE

Generate NT password hash:

3proxy_crypt MySecretPassword

Result:

NT:3F7E6D8D96E8E7A9B0C1D2E3F4A5B6C7

Generate BLAKE2b password hash with salt:

3proxy_crypt MySalt MySecretPassword

Result:

CR:$3$MySalt$...

Using in 3proxy.cfg:

users user1:CR:$3$MySalt$...

NOTES

The NT hash uses the RSA MD4 Message-Digest Algorithm. The BLAKE2b hash uses the BLAKE2 cryptographic hash function.

When a password hash is prefixed with NT: or CR: , 3proxy uses the corresponding algorithm to verify passwords instead of comparing cleartext strings.
