Vit 1.81

Secure Remote Password (SRP) is a password-based authentication and key exchange mechanism where no information about the password is leaked during the authentication process. It does not require any public key cryptography, yet even if one were to eavesdrop on the authentication process, no information which would aid in guessing the password can be obtained (in theory). There are some reworked Telnet and FTP clients and servers available already.

Vit 2.29

Sendmail-TLS is a wrapper for Sendmail which allows for clients to make a secure (SSL) connection to their mailserver as described in RFC 2487. The connection is internally forwarded to sendmail and does not require sendmail to be running on port 25. Clients which support this currently are Netscape Messenger, Microsoft Outlook, and Microsoft Outlook Express.

Given a threshold t, sharesecret splits a secret into parts, such that exactly t parts are needed to reconstruct the secret. If you have fewer parts you know only the approximate or exact length of the secret.

Download Website Updated 19 Aug 2001 shash

Vit 1.51

shash is a program which produces message digests for files, and checks whether the digest remains the same (i.e., whether the files changed). Since anyone can generate the message digest, it may not be suitable for some security-related applications. Because of this, shash also supports HMAC (rfc2104), which is a mechanism for message authentication using cryptographic hash functions. shash can use a key with a hash algorithm to produce hashes that can only be verified with the same key. This way, you can securely check whether files in a filesystem were altered.

Download Website Updated 30 Jan 2001 shsecret

Vit 1.00

shsecret takes a file and splits it into N parts of equal size such that any M parts can be used to reconstruct the secret, but fewer than M will give absolutely no information about the secret. This program is written in strict ANSI C, so it should be completely portable. It is also hopefully simpler and more efficient than other implementations of the same algorithm.
