- encryption - Decrypt SHA1 value with C# - Stack Overflow
I have a PHP web service that I've discovered is passing my C# a SHA-1 encrupted value The sample data that is passed to me is
- How to Encrypt and Decrypt Data Using a Symmetric Key (C# . . .
Description These code samples demonstrate how to generate a persistent (i e non-random) symmetric key using the Rijndael and use this key to encrypt and decrypt a text string The key is derived from several characteristics passed to encryption and decryption routines
- OpenSSL Command-Line HOWTO - madboa. com
Introduction The openssl command-line binary that ships with the OpenSSL libraries can perform a wide range of cryptographic operations It can come in handy in scripts or for accomplishing one-time command-line tasks Documentation for using the openssl application is somewhat scattered, however, so this article aims to provide some practical examples of its use
- RSA (cryptosystem) - Wikipedia
RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private) In RSA, this asymmetry is based on the practical difficulty of the factorization of the product of two large prime numbers, the "factoring
- Cryptography - Wikipedia
The first use of the term cryptograph (as opposed to cryptogram) dates back to the 19th century - it originated in The Gold-Bug, a novel by Edgar Allan Poe Until modern times, cryptography referred almost exclusively to encryption, which is the process of converting ordinary information (called plaintext) into unintelligible text (called ciphertext)
- encryption - How to decrypt a password from SQL server . . .
I believe pwdencrypt is using a hash so you cannot really reverse the hashed string - the algorithm is designed so it's impossible If you are verifying the password that a user entered the usual technique is to hash it and then compare it to the hashed version in the database
- XML Encryption Syntax and Processing Version 1. 1
The CipherData element envelopes or references the raw encrypted data A CipherData element must have either a CipherValue or CipherReference child element If enveloping, the raw encrypted data is the CipherValue element's content; if referencing, the CipherReference element's URI attribute points to the location of the raw encrypted data
- XML Encryption Syntax and Processing - World Wide Web . . .
This document specifies a process for encrypting data and representing the result in XML The data may be arbitrary data (including an XML document), an XML element, or XML element content The result of encrypting data is an XML Encryption element which contains or references the cipher data This
