Here is how I initialize MessageDigest And here is how digest to get bytes for password which I later convert to string (no issue there) Now assume the password is “Password@1”. Here is the output first time (apologies for long text below) 115,83,48,-2,41,29,-99,71,-54,-53,-26,-67,-118,48,-75,77,1…

For PBKDF2, using HMAC-SHA256 is more secure than using HMAC-SHA-1?
I’m looking for the proper Java algorithm for password encryption, and I found that Java SDK provides PBKDF2WithHmacSHA1, but not PBKDF2WithHmacSHA256. I heard that HMAC-SHA256 will take more time than HMAC-SHA-1 does. Since system resources are limited, I’m going to apply different iteration valu…
How to make “MessageDigest SHA-1 and Signature NONEwithRSA” equivalent to “Signature SHA1withRSA “
I am interested in applying a SHA-1 hash with RSA signature to some data, but I need to do it in two steps – apply hash first and then sign the data. The Signature.sign() function appears to create a more complex (ASN.1?) data structure that is ultimately signed (see this question). How can I make the t…
