Invalid AES key length: 20 bytes (Java 11)

I am trying to generate a key using Java. To be honest I am not that experienced with keys, password, ciphers and encryption. And from whatever I have searched from this site, I see it as a very common problem. I did some reading and came up with this code that I wrote: This is modified from an answer that

AES Encryption algorithms and padding scheme

Hello currently i have to do an AES encription and send it to an external SW but i am having trouble with the sonarqube. this is the relevant part of my current code: Is a little spaguetti cause it´s recyclated for an old code (TripleDES) sorry for that. But we can get the gist of it that`s that we are

best way to store aes encrypted data

What is the best/secure/easy to implement way to (locally) store data which has been encrypted using AES encryption? There doesn’t seem to be a proper guide or standard way to store the data, but after looking at some projects that use AES encryption, these seem to be the formats that come most: XML Text files csv for csv – the

Decrypt Java AES/CBC/PKCS5Padding with CryptoJS

I have some problem decrypting text with CryptoJS that has been encrypted with Java. The decryption should be done with AES/CBC/PKCS5Padding. The encrypted string is base64 encoded and I decode it before trying to decrypt the string. This is how the Java code looks like: And this is how I attempt to decrypt it in CryptoJS. SharedSecretKey is both the

Decrypt using AES-256-ECB in Java

I have encrypted the string in PHP using AES-256-ECB. I would like to decrypt the same using Java/Scala? I am seeing the following error? how can we decrypt the same using Java? Note: (decryption in PHP is working as expected) but I want to do this in Java Answer The key has to be exactly 256 bit long. Clearly the

Decrypt a Java AES encoded String in Dart

I need to decrypt an AES (PKCS#7) encoded string in my Flutter mobile application. The string is got from a QR Code, which has been generated from a Java application and contains the AES encoded String. The Java encoding : Output : AIRTEuNmSuQtYuysv93w3w83kJJ6sg7kaU7XzA8xrAjOp-lKYPp1brtDAPbhSJmT The Dart decoding : Output : Y��=X�Rȑ�”;12 You can see that only a part of the string

Cipher functions : WRONG FINAL BLOCK LENGTH Android Studio

There are a lot of threads on stack overflow with this topic, and always the same solutions, but these doesn’t work for me. I am looking for a way to decrypt the value byte[] encrypted and return byte[] decodedBytes. With the method AESCrypt. I use compile ‘com.scottyab:aescrypt:0.0.1’ With the value Cipher, i use it like that. Whatever i do, i

Java 7 support of AES-GCM in SSL/TLS?

According to Java 7 documentation as well as third party vendors, it appears Java 7 should support AES-GCM suites: ibm java 7 java 7 ssl doc I was hitting some errors in negotiation between client and server unable to negotiate a cipher due to restricting it to only the AES-GCM ciphers. After investigation I found that it appears that the
