-----BEGIN PGP SIGNED MESSAGE----- I've written an implementation of SHA-1 in C. Public domain, so you can hack it to your hearts content and/or use it however you want. You can download it from http://www.edmweb.com/steve/sha1.c It's not hard to use. Allocate a SHA1_CTX, initialize it with SHA1Init() run over the data with SHA1Update() and finally extract the result using SHA1Final(). Or just compile the program as-is and use it to hash files. It's reasonably fast (the 80 core SHA operations look good) but I'm certain that there's room for improvement. Tested under FreeBSD 2.1.0-RELEASE on an i486SX. The three test vectors from FIPS PUB 180-1 hash correctly. ===================================================================== | Steve Reid - SysAdmin & Pres, EDM Web (http://www.edmweb.com/) | | Email: steve@edmweb.com Home Page: http://www.edmweb.com/steve/ | | PGP (2048/9F317269) Fingerprint: 11C89D1CD67287E68C09EC52443F8830 | | -- Disclaimer: JMHO, YMMV, TANSTAAFL, IANAL. -- | ===================================================================:) -----BEGIN PGP SIGNATURE----- Version: 2.6.3ia Charset: noconv iQEVAwUBMksSsNtVWdufMXJpAQFV3AgApaK+upwWtBJZUwq5Pr4cpvjWQcxFHxv6 XEoZmwgwzR94lpjdEK5GPXt7U9HTp+xiwiaeQ7Hjg+iuR/qtofwZlZhQ5EmyBl2M 8rnFSRgwR4NH1y2PwAxQKSo2SaHU8JZ3X3D6Yk1WXAqk90vN8dzQAIa8B409IuhM tBPixrS6d0KsySSOHQkWO7Mqij43wZOnrgikJF3IDCvSf0us8gGC9wZjdIax3Rgr soswtQvT6QpZDZ/+39UiA2RSMFuER/S3NbZZSJdfIGK1XzUeU2MUC4NmURlc/ntz 3B1pd+jovxuHW1D/TQ2jHSIdg1Yol/zeu1OeuuhL37QOQAVkupgVUA== =B73M -----END PGP SIGNATURE-----
