An implementation of a basic keyword transposition cipher in Javascript with zero dependencies.
const C = require('js-ktc');
let ktc = new C('secret')
ktc.encrypt('CRYPTOLOGY')
// 'JHQSU XFXBQ '
ktc.decrypt('JHQSU XFXBQ')
// 'CRYPT OLOGY '
✅ Easy to use
✅ Extensible
✅ Test coverage
✅ Lots of comments (good for education)
✅ No bloat (zero dependencies)
✅ MIT license
npm install js-ktc
- Require
const C = require('js-ktc'); - Initialize
let ktc = new C('secret') - Encrypt
ktc.encrypt('CRYPTOLOGY') - Decrypt
ktc.decrypt('JHQSU XFXBQ')
The basic implementation only works with A-Z though it can easily be extended to support other characters.
