An in-depth analysis of the implementation principle of sha1 algorithm
1. Basic introduction SHA (Security Hash Algorithm) is a standard Hash algorithm designed by NIST and NSA in the United States. SHA is used in DSS, the standard algorithm for digital signatures, and is also a highly secure Hash algorithm. SHA-1 is the first generation SHA algorithm standard, and later SHA-224, SHA-256, SHA-384 and SHA-512 […]
[Front-end knowledge] Front-end encryption algorithm (base64, md5, sha1, escape/unescape, AES/DES)
Front-end encryption algorithm 1. base64 encryption and decryption algorithm Introduction: The Base64 algorithm uses 64 characters (A-Z, a-z, 0-9, +, /) to represent 64 possibilities of binary data, encoding every 3 bytes of data into 4 printable characters. If the number of bytes is not a multiple of 3, padding will occur. advantage: Printable characters: […]

Network security – Base64 encoding, MD5, SHA1-SHA512, HMAC (SHA1-SHA512) hashing
1. Base64 encoding Base64 encoding requires converting three 8-bit bytes (3*8=24) into four 6-bit bytes (4*6=24), and then in Two 0s are added in front of the 6 bits to form a byte of 8 bits, so that the effective bits of each byte are 6 bits, and the value range is 0~630 ~ (2^6 […]
SHA algorithm (sha0 sha1 source code modification)
SHA (Security Hash Algorithm) is a standard Hash algorithm designed by NIST and NSA in the United States. SHA is used in DSS, a standard algorithm for digital signatures, and is also a highly secure Hash algorithm. SHA-1 is the first generation of SHA algorithm standard, and later SHA-224, SHA-256, SHA-384 and SHA-512 are collectively […]
