- Dear fellows,
-
- The project: The implementation of UFC (Ultra Fast Crypt) on UNI-C's
- CM200 is now finished.
-
- The work was done by Michael Glad, who is also the auther of UFC.
- The CM200 is a small Connection Mashine (parallel computer)
- with 8K CPUs from Thinking Machines Corporation.
-
- Below are the results:
-
- - The C* (C-star) version of UFC can crypt 55,000 words pr. second.
- It is higly optimized and uses special PARIS functions in all the
- time comsuming parts.
-
- - The Fortran version af UFC can "only" crypt 25,000 words pr. second.
-
- - The C* version implemented as the standard crypt() function
- can crypt 53,000 words pr. second.
-
- The task is embarrassing parallel and is therefore linarly scalable.
- So on the largest CM200 (64 K processors) the crypt() function can
- crypt 424,000 words pr. second.
-
- At the moment, the Fortran version of UFC can crypt 85,000 words pr.
- second on a small CM-5 (128 nodes) with vector units and it is NOT
- optimized yet.
-
-
- Does anyone know who is running the fastest password cracking program
- (crypt() function) on a SINGLE machine?
-
- Please do * NOT * respond if your answer cant'be documented or verified!
- There are just too many rumors around . . .
-
-
- Thanks in advance
