Hash work is done by a computer algorithm, and once the data has been transformed, it can't be returned to the original state. Common Hashing Algorithms All hashing algorithms work in a similar manner. Users in
The algorithm is designed in such a way that no two hashes are the same for two different texts. And it is impossible (almost!) to go back from the hash value to the original text. It’s kind of like a cow moving on stairs – it can move upstairs but not down!! Anyway, looping...
Cryptographic hashesMaps data from any length to a fixed-length byte sequence. Hashes are statistically unique; a different two-byte sequence will not hash to the same value. Secret-Key Encryption Secret-key encryption algorithms use a single secret key to encrypt and decrypt data. You must se...
Popular hashing algorithms include Secure Hash Algorithms and Message Digest Algorithm 5. How to break encryption For any cipher, the most basic method of attack is brute force -- trying each possible decryption key until the right one is found. The length of the key determines the number of ...

在工作和学习的过程中笔者经常需要快速的进行数据加解密的操作,然而,我发现现有的加密工具如openssl,虽然功能全面,但使用起来并不直观,尤其是对于非专业人士来说。 举个例子,当我想对一个简单的字符串“hello,world”进行AES加密时,使用openssl需要执行一串相对复杂的命令,如echo -n "hello,world" | openssl enc ...
A proxy re-encryption scheme is a tuple of algorithms (KeyGen, ReKeyGen, Enc, ReEnc, Dec): • KeyGen(n)→(pkA,skA). On input security parameter n, the key generation algorithm KeyGen outputs a pair of public and secret keys (pkA,skA) for user A. • ReKeyGen(pkA,skA,pkB,skB)...

Compared to public key (asymmetric) cryptography, symmetric cryptography is faster and employs simpler algorithms as basic building blocks (e.g. Message Authentication Code (MAC), hash function) that have linear computational complexity, and so can ensure authenticity of the message source and ...
