I don't understand why a hash doesn't need a key, what a salt is the difference between MD5, SHA1, SHA256, or even the difference between a hash and an encryption!. Generate the SHA1 hash of any string. To fix this you can test the length of the hash and append equal signs "=" until it is the length is a multiple of 4. rsa: Package rsa implements RSA encryption as specified in PKCS#1. It was recently demonstrated that it is feasible to create SHA-1 collisions. Use a program to take the SHA256 of the saved file. Java support many secure encryption algorithms but some of them are weak to be used in security-intensive applications.
