A Brief Intro To Cryptographic Hashes/MD5

2008-05-10 20:33:02 by Editor in Irongeek's Security Site
 
...Cryptographic Hashes/MD5 A cryptographic hash function takes an input and returns a fixed size string that corresponds to it, called a hash. Cryptographic hashes have a lot of uses, some of which are: detecting data changes, storing or generating passwords, making unique keys in databases and ensuring message integrity. This video will mostly...

A cryptographic hash function reading guide

2007-11-23 16:01:18 by George Danezis in Light Blue Touchpaper
 
...cryptographic hash function NIST has announced a competition to determine the next Secure Hash Algorithm, SHA-3. SHA-0 is considered broken, SHA-1 is still secure but no one knows for how long, and the SHA-2 family are desperately slow. (Do not even think about using MD5, or MD4 for which Prof. Wang can find collisions by hand, but RIPEMD-160...

More trustworthy election systems via SDL?

2008-02-04 23:34:00 by sdl in The Security Development Lifecycle
 
...cryptographic functions are implemented incorrectly, based on weak algorithms with known flaws, or used in an ineffective or insecure manner. Of particular concern is the fact that virtually all cryptographic key material is permanently hardcoded in the system (and is apparently identical in all Sequoia hardware shipped to different...

The Skein Hash Function

2008-10-29 04:35:29 by schneier in Schneier on Security
 
...cryptographic hash functions. Its design combines speed, security, simplicity, and a great deal of flexibility in a modular package that is easy to analyze Skein is fast. Skein-512 -- our primary proposal -- hashes data at 6.1 clock cycles per byte on a 64-bit CPU. This means that on a 3.1 GHz x64 Core 2 Duo CPU, Skein hashes data at 500...

America's Next Top Hash Function Begins

2008-11-20 02:00:00 by Bruce Schneier in Wired Security
 
...cryptographic primitive, and the most poorly understood. You can think of them as fingerprint functions: They take an arbitrary long data stream and return a fixed length, and effectively unique, string. The security comes from the fact that while it's easy to generate the fingerprint from a file, it's infeasible to go the other way and...

SDL and the OWASP Top Ten

...Cryptographic Storage 9. Insecure Communications 10. Failure to Restrict URL Access Looking at this list, we address Cross-Site Scripting issues in the SDL very thoroughly today: we have several XSS detection and prevention tools our development teams use to defend against XSS attacks. (As Ive written here before, some of these tools are...

Can I just comment out these lines of code?

...cryptographic library package . By removing this code, the strength of the cryptographic key material was reduced to a point where cracking the key would take minutes instead of decades. The unfortunate thing about cryptography and randomness is that good and bad can be virtually indistinguishable, and in this case the result still looked so...
