There was a lot of news in the past year about exploitable weaknesses in cryptography which originated from weak random number generators. In some cases it was negligence on side of the developers, in ...
I am concerned that a SHA-1 PRNG cannot produce an AES-256 cipher key with the expected 256 bits of security, or indeed any secure cipher key where over 165 bits of security are expected. The SHA-1 ...
I know from experience that reading from /dev/random blocks when the Linux kernel entropy pool runs out of entropy. Also, I've seen many articles and blog entries stating that when running on Linux, ...
How to generate a secure random number bit length is 256 bits using Java. What is the different between: SecureRandom random = new SecureRandom(); and SecureRandom prng = ...
When generating randomness using SecureRandom in Android, I want to select /dev/random or /dev/urandom as the seed source. It can be done in java.security file on Linux and Windows systems but there's ...
