AES enryption in Javascript and Decryption in Java using a static SALT and IV

I’m working on AES encryption

I want to encrypt a string in JavaScript and using that ciphertext which is generated during encryption I want to decrypt it in JAVA. I want to use static SALT and IV on both side i.e. common SALT and IV.

I encrypted the string in java Script and decrypted in JAVA but using random SALT and IV and not static and by using API calls for sending the encrypted text and salt and IV to the java program

What actually I want is to avoid the use of API calls and do it using static IV and Salt

Also in #JavaScript _↴
