This tool provides encryption functions for algorithms such as MD5, hash, SHA-1, SHA-2, SHA-256, SHA-512, SHA-3, RIPEMD-160, and includes detailed explanations of the related encryption algorithms. Welcome to use it if needed.
I. MD5 Hash Encryption Algorithm
MD5 stands for Message-Digest Algorithm 5, which is used to ensure the integrity and consistency of information transmission. It is one of the widely used hashing algorithms in computers (also known as digest algorithm or hash algorithm), and has been implemented in mainstream programming languages. The basic principle of the hashing algorithm is to process data (such as Chinese characters) into another fixed-length value. The predecessors of MD5 include MD2, MD3, and MD4.
MD5 was once widely used in the security field. However, due to the continuous discovery of weaknesses in MD5 and the continuous improvement of computing power, it is now possible to construct two messages with the same MD5, making this algorithm no longer suitable for the current security environment. Currently, MD5 calculations are widely used for error checking. For example, in some BitTorrent downloads, the software checks the integrity of the downloaded fragments by calculating MD5.
MD5 is an algorithm that takes input of variable length and outputs a fixed-length of 128-bits. Through the program flow, four 32-bit data are generated and finally combined into a 128-bit hash. The basic approach is to perform modulo operations, remainder extraction, length adjustment, and iterative operations with the link variable to obtain the result.
II. SHA-1 Hash Encryption Algorithm
SHA-1 is widely used in many security protocols, including TLS and SSL, PGP, SSH, S/MIME, and IPsec, and was once considered a successor to MD5
However, the security of SHA-1 is now seriously questioned by cryptographers.
III. SHA-2 Hash Encryption Algorithm
3.1 SHA 256 Hash Encryption Algorithm
3.2 SHA 512 Hash Encryption Algorithm
SHA-224, SHA-256, SHA-384, and SHA-512 are collectively referred to as SHA-2.
The new hash functions have not undergone detailed scrutiny by the public cryptographic community like SHA-1, so their cryptographic security is not widely trusted.
Although no effective attacks on SHA-2 have yet been discovered, its algorithm is still similar to SHA-1; therefore, some people have begun to develop alternative hash algorithms.
IV. SHA-3 Hash Encryption Algorithm
Output Length:
SHA-3, previously known as the Keccak algorithm, is a cryptographic hash algorithm.
SHA-3 is not intended to replace SHA-2, as SHA-2 does not have any significant weaknesses currently.
Due to successful attacks on MD5 and theoretical methods against SHA-0 and SHA-1, NIST felt the need for a new, alternative cryptographic hash algorithm that differs from previous algorithms, which is now SHA-3.
V. RIPEMD-160 Hash Encryption Algorithm
RIPEMD-160 is a 160-bit cryptographic hash function.
It was designed to be a replacement for the 128-bit hash functions MD4, MD5, and RIPEMD.
RIPEMD was developed within the framework of the EU project RIPE (RACE Integrity Primitives Evaluation, 1988-1992).
