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,-75,77,13,100,42,70,-72,110,-85,23,-38,119,-110,-15,121,3,-25,114,-68,109,-108,94,-122,65,-62,10,-90,8,-125,114,-118,51,-51,89,127,55,37,83,-126,56,-31,-27,-49,-60,25,74,-80,-110,23,45 And here is output second time onwards. It remains same after this. -62,-50,45,-44,91,-86,16,90,85,53,101,-122,51,12,-82,52,-123,-101,-10,-28,-108,114,120,-96,84,-23,38,-75,78,67,36,-93,-88,-11,79,76,126,-34,-2,109,76,-31,-30,-86,-28,13,-91,-22,-65,-128,108,-47,15,19,95,60,-30,-123,-4,20,-64,21,-1,7 Can some one please

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 values to make them most secure as long as service requirements can bear it. Even with the
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 two equivalent without using
