Decryption issue with Triple DES algorithm. #152

Open abhinandanpatilInd opened 6 years ago

abhinandanpatilInd commented 6 years ago

I'm doing the Triple DES encryption with below details:

  1. HEX Key : 579D2D852F2F3BABABBD71B7BD3B7D11
  2. Data to encrypt : 141234FFFFFFFF

Code I used: var encrypted = CryptoJS.TripleDES.encrypt('141234FFFFFFFF', '579D2D852F2F3BABABBD71B7BD3B7D11'); console.log("DES3 encrypted text:"+encrypted); var decrypted = CryptoJS.TripleDES.decrypt(encrypted, '579D2D852F2F3BABABBD71B7BD3B7D11'); console.log("DES3 decrypted text:"+decrypted);

Issues I'm facing:

  1. Each time I'm getting different out put of above code
  2. Decryption doesn't producing clear text which was supplied to encryption.

Any inputs on above are highly appreciated!!

Try encoding the decrypted result in UTF8: decrypted.toString(CryptoJS.enc.Utf8). It should give you the original string.

As for issue 1: You get different encrypted value each time because each time a new random initialization vector is generated.
