Understanding SecureCRT and Licensing
SecureCRT is a popular SSH client software used for secure remote access to servers and network devices. It offers a free trial period, but a valid license key is required for continued use beyond that.
GitHub and Free License Keys
While GitHub is an excellent platform for open-source projects and collaborative development, it's not typically a place to find free license keys for commercial software like SecureCRT.
Vanilla SecureCRT
SecureCRT is a commercial product developed by Vanila. Officially, you can get a free trial from the SecureCRT website. SecureCRT 9
How to obtain a free or public license
Sometimes people on the Internet provide public licenses. But I couldn't find any public license keys for SecureCRT 9.1. But here are some steps:
Alternatives to SecureCRT
If you're looking for free alternatives to SecureCRT, you can consider:
These alternatives may not offer all the features of SecureCRT, but they can provide basic SSH client functionality.
Additional notes
// handler.js – serverless function that issues a free token
const jwt = require('jsonwebtoken');
const axios = require('axios');
const PRIVATE_KEY = process.env.PRIVATE_KEY; // PEM string
const GIST_ID = process.env.GIST_ID; // repo‑wide gist for storing tokens
exports.handler = async (event) =>
const code, state = JSON.parse(event.body);
// 1️⃣ Exchange code for access token
const tokenRes = await axios.post(
'https://github.com/login/oauth/access_token',
client_id: process.env.CLIENT_ID,
client_secret: process.env.CLIENT_SECRET,
code, state ,
headers: Accept: 'application/json'
);
const ghToken = tokenRes.data.access_token;
// 2️⃣ Get user info + contributions
const userRes = await axios.get('https://api.github.com/user',
headers: Authorization: `token $ghToken`
);
const username = userRes.data.login;
const contribRes = await axios.post(
'https://api.github.com/graphql',
query: `
query
user(login:"$username")
contributionsCollection
contributionCalendar totalContributions
`,
headers: Authorization: `bearer $ghToken`
);
const contributions = contribRes.data.data.user.contributionsCollection.contributionCalendar.totalContributions;
// 3️⃣ Eligibility check (e.g., >=5 contributions)
if (contributions < 5)
return statusCode: 403, body: JSON.stringify(msg:'Not eligible') ;
// 4️⃣ Sign JWT (30‑day free tier)
const payload = $userRes.data.id`,
iat: Math.floor(Date.now()/1000),
exp: Math.floor(Date.now()/1000) + 30*24*60*60,
tier: 'free',
features: ['session_logging', 'max_sessions:5']
;
const token = jwt.sign(payload, PRIVATE_KEY, algorithm: 'RS256' );
// 5️⃣ Write token to a private gist (named after the user)
await axios.patch(
`https://api.github.com/gists/$GIST_ID`,
files: [`$username.json`]: content: token ,
headers: Authorization: `token $ghToken`
);
return statusCode: 200, body: JSON.stringify( token ) ;
;
The client simply reads its own private gist (https://api.github.com/gists/<id>/contents/<username>.json) and validates the JWT.
The legitimate way to obtain a SecureCRT license involves purchasing it directly from VanDyke Software or through authorized resellers. Once purchased, you receive a license key that activates the software for use.
SecureCRT is a robust client for Windows, macOS, and Linux that offers a comprehensive set of tools for secure access to remote systems. Its features include:
| Component | Tech Stack | Key APIs |
|-----------|------------|----------|
| OAuth | requests‑oauthlib (Python) / electron‑oauth2 (JS) | GET https://github.com/login/oauth/authorize |
| Eligibility Engine | Serverless (Node.js) | GitHub GraphQL API → contributionsCollection |
| JWT Signing | pyjwt or jsonwebtoken | RS256 with vendor‑held private key |
| Gist Management | GitHub REST API (/gists) | POST /gists, PATCH /gists/:id |
| Revocation List | Public repo securecrt-revocations (JSON) | GET https://raw.githubusercontent.com/.../revoked.json |
| Client Validation | Built‑in SecureCRT‑Lite module (LicenseManager) | jwt.verify(token, publicKey) |
