Free sha software for linux

Digest::SHA1 is a Perl interface to the SHA-1 algorithm.

SYNOPSIS

# Functional style
use Digest::SHA1 qw(sha1 sha1_hex sha1_base64);

$digest = sha1($data);
$digest = sha1_hex($data);
$digest = sha1_base64($data);
$digest = sha1_transform($data);


# OO style
use Digest::SHA1;

$sha1 = Digest::SHA1->new;

$sha1->add($data);
$sha1->addfile(*FILE);

$sha1_copy = $sha1->clone;

$digest = $sha1->digest;
$digest = $sha1->hexdigest;
$digest = $sha1->b64digest;
$digest = $sha1->transform;

The Digest::SHA1 module allows you to use the NIST SHA-1 message digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 160-bit "fingerprint" or "message digest" of the input.

The Digest::SHA1 module provide a procedural interface for simple use, as well as an object oriented interface that can handle messages of arbitrary length and which can read files directly.

Hasher is a tool to help programmers implement checksum algorithms and standard hashing into their own software.
Written entirely in C# and designed for use in the .NET Framework, Hasher providers a uniform interface to easily use any of the algorithms contained within this library in other programs.
Hasher is planned to encapsulate a wide variety of cryptographic hashing and checksum algorithms.
Focusing on compatibility, speed, and ease-of-use, Classless.Hasher currently supports over 25 different algorithms including the "basics" such as CRC, MD5, and SHA, as well as others like HAVAL, Tiger, Snefru, and Whirlpool.
Enhancements:
- Hasher rises from the dead!
- Fixed CRCStandards for CRC8 and CRC32.
- Fixed CRC handling when the Order was 64bits.
- Removed the REVERSED CRCStandards.
- Added CRCStandards for CRC64_ISO and CRC64_ECMA.
- Changed CRCStandard CRC16 to CRC16_IBM.
- Renamed CRC16_CCITT_REVERSED to CRC16_XMODEM.
- Fixed nasty bug that broke MD4, MD5, the RIPEMDs, Tiger, and the SHAs when large datasets were processed.
- Added support for creating Panama hashes.
- Fixed the NAnt build script to better support Mono and .NET v2.0.

ObexPushD is a software used to receive files via Bluetooth, IrDA and TCP. This program should work with many mobile devices like PDAs and mobile phones.

strongSwan is an OpenSource IPsec implementation for the Linux operating system. strongSwan is based on the discontinued FreeS/WAN project and the X.509 patch which we developped over the last three years.
In order to have a stable IPsec platform to base our future extensions of the X.509 capability on, we decided to lauch the strongSwan project.
Main features:
- runs both on Linux 2.4 (KLIPS) and Linux 2.6 (native IPsec) kernels
- strong 3DES, AES, Serpent, Twofish, or Blowfish encryption
- Authentication based on X.509 certificates or preshared keys
- Powerful IPsec policies based on wildcards or intermediate CAs
- Retrieval and local caching of Certificate Revocation Lists via HTTP or LDAP
- Full support of the Online Certificate Status Protocol (OCSP, RCF 2560).
- Optional storage of RSA private keys on smartcards or USB crypto tokens
- Smartcard access via standardized PKCS #11 interface
- PKCS #11 proxy function offering RSA decryption services via whack
- NAT-Traversal (RFC 3947) and support of Virtual IPs and IKE Mode Config
- CA management (OCSP and CRL URIs, default LDAP server)
- Dead Peer Detection (DPD, RFC 3706)
- Group policies based on X.509 attribute certificates ( RFC 3281)
- Generation of default self-signed certificates during strongSwan setup
Whats New in 2.8.0 Stable Release:
- The implementation of the IKE Mode Config push mode allows interoperability with Cisco VPN gateways.
- By setting "modeconfig=push", strongSwan will wait for the peer to push down a virtual IP address that can be used within an IPsec tunnel.
- The default value of the new keyword is "modeconfig=pull".
- The command "ipsec statusall" now shows "DPD active" for all ISAKMP Security Associations that are under active Dead Peer Detection control.
Whats New in 4.0.7 Development Release:
- Extended authentication (XAUTH) in conjunction with IKE Main Mode authentication (RSA and PSK) is now possible with most VPN clients and gateways (e.g. Cisco, NCP, Shrew, etc.).
Whats New in 2.8.3 Stable Release:
- A bug in the computation of the SHA-512-HMAC function was fixed.
- The SHA-384 hash and HMAC functions were implemented.
- SHA-2 signatures are now supported in X.509 certificates.
- Automatic test vector-based self-tests of all hash functions (MD5, SHA-1, SHA-2) during pluto startup was introduced to increase the reliability of the software.

sftpup is used for uploading files to ftp servers and keep them consistent to a local directory.

To use sftpup go follow these steps:

1. Create a directory for your work, e.g. www where all files will be stored. For example, if you create your websites via XML and XSLT, make www the target for each generated file.
2. Upload all files to the ftp server. Your server directory and www are now in a consistent state. sftpup saves the state of www by calculating SHA hashes for each file. To initialize, execute:

sftpup --init your-config-file

The hashes are stored in the file given by hashfile in your-configfile.
3. If you change a file or directory (modified, deleted, added etc.) and want to do an update the ftp server, type:

sftpup --update your-config-file

sftpup compares HTML files with stored hashes and lists differences.This list is then used to make send appropriate commands to the ftp server.
4. To test what actions would be done, you can do a socalled dry-run by typing:

sftpup --dry-run your-config-file

sftpup then prints a list of commands and files/directories.

XySSL is a cryptographic library written in C. It currently features several ciphers (AES, Triple-DES, and ARC4), hash functions (MD{2,4,5}, SHA-1, and SHA-256), and RSA and X.509 reading support.
XySSL project also implements the Secure Sockets Layer version 3 protocol (SSLv3), as well as the Transport Layer Security version 1 protocol.
Main features:
- AES, Triple-DES, DES, ARC4
- MD2, MD4, MD5, SHA-1, SHA-256
- HAVEGE random number generator
- RSA with PKCS#1 v1.5 padding
- SSLv3 and TLSv1 client support
- X.509 certificate reading
Enhancements:
- This releases fixes several bugs and adds nine demonstration programs.

SquTUN creates an AES-encrypted, SHA-1 authenticated UDP tunnel over which IP packets received from a TUN interface are encapsulated and transmitted.
It is intended to replace installations that are currently using CIPE for point-to-point VPNs. Unlike CIPE, SquTUN doesnt require a custom kernel module.
Furthermore, SquTUNs implementation and interface are much less complex, leading to greater confidence in its correctness.
Enhancements:
- This release zeroes out the remainder of the last plaintext block before sending, to avoid sending uninitialized (and possibly private) data.
- It also fixes type mismatch warnings with syslog/printf under -Wall.
