Text Security

Simple API that authenticates users via login:password using SHA-512 crypt ($6$) and returns a decrypted access string.

How it works

1. GET /<prefix>/login:password
2. Server looks up the user in a JSON file
3. Verifies the password against the stored SHA-512 crypt hash
4. Decrypts the access field using the password (OpenSSL AES-256-CBC)
5. Returns the decrypted access string as text/plain

JSON file format

{
  "users": [
    {
      "login": "ivan",
      "password": "$6$O0pY1wVZvyPo9g9L$...",
      "access": "U2FsdGVkX1+YNcwyHYyz..."
    }
  ]
}
