I\'ve read a couple times that MD5 is not an encryption, e.g. on MD5 ... Encryption? or Command Line Messa开发者_StackOverflow中文版ge Digest Utility.
If I generate a message digest (for a security feature in my app) using this Java code: java.security.MessageDigest saltDigest = MessageDigest.getInstance(\"SHA-256\");
I am using java message digest to create MD5 hash, which is used for authentication. The MD5 hash is stored in the database as varchar2. I did a test to create a user on my tomcat server on my local l
I have a sample application which generates a SHA1 hash in PHP as follows. base64_encode(pack(\'H*\', sha1($pass)));
Ok, I\'m a little confused. I\'m trying to use MessageDigest to store my passwords in the database as MD5 hashes, and then pull the hash out to check a user\'s password when they try to log in.
I want to create a Sha1 me开发者_JAVA技巧ssage digest, and it should use my private key as input along with the plain text.
I\'ve been doing some preliminary research in the area of message digests. Specifically collision attacks of cryptographic hash functions such as MD5 and SHA-1, such as the Postscript example and X.50
It is trivial to use a secure hash function like SHA-256, and continuing to use MD5 for security is reckless behavior. However, there are some complexities to hash function vulnerabilities that I woul
