• File modules/sha1/sha256.bench — part of check-in [333f22feef] at 2005-10-25 01:26:40 on branch trunk — Added basic benchmarks for the lot of checksums and hashes. Fixed ability to use critcl for base64 and rc4 benchmarks. (user: andreas_kupries size: 1308)

# Tcl Benchmark File
#
# This file contains a number of benchmarks for the 'sha2' module.
# This allow developers to monitor/gauge/track package performance.

# (c) 2005 Andreas Kupries <[email protected]>

# We need at least version 8.2 for the package and thus the
# benchmarks.
