Amazon Glacier DES.java generates the sysmetric key using DES algorithm. Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). How do I convert a String to an int in Java? rev 2020.12.18.38240, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, Thanks a lot.But in fact,this method uses only two key to encrypt the message:"HG58YZ3CR9" and the "IvParameterSpec iv = new IvParameterSpec(new byte[8]);" . javax.crypto.Cipher Class provides the functionality of a cryptographic cipher for encryption and decryption.

Here's what I've been working with so far: ** note, I am not returning the BASE64 text from the encrypt method, and I am not base64 un-encoding in the decrypt method because I was trying to see if I was making a mistake in the BASE64 part of the puzzle. After some comparative testing of my results against some 3DES calculators designed for the financial world I found the the value “DESede/ECB/Nopadding” is more suited for the the specific task. Leave a comment. Just paste your text in the form below, enter password, press Triple DES Decrypt button, and you get decrypted message. Classic ASP Java Libs for Android. your coworkers to find and share information. net calls JAVA WEBSERVICE, data is encrypted with 3DES, which involves the consistency of 3DES in two languages,Share the following information,The keys are Base64 The data actually passes across a network and comes back to the same laptop now, but that will change once this is out of development. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. But it still uses ECB which is a bigger mistake. Symmetric ciphers use the same (or very similar from the algorithmic point of view) keys for both encryption and decryption of a message.
