! expr - Logical not. % expr1 % expr2 - Returns the remainder after expr1/expr2.. Examples: > SELECT 2 % 1.8; 0.2 > SELECT MOD(2, 1.8); 0.2 & expr1 & expr2 - Returns the result of bitwise AND of expr1 and expr2. To obtain the PKZIP (also JDK TM java.util.zip.CRC32 class) behavior: Initialize with 0xFFFFFFFF via the init() method Algorithm specifics: The input data is reversed (reflected) The ISO 3309 algorithm is used with the polynomial value 0x04C11DB7; The resulting 32 bit FCS is reversed (reflected) The reversed 32 bit FCS is xor'd with OxFFFFFFFF.
Dec 14, 2015 · The program sha256sum is designed to verify data integrity using the SHA-256 (SHA-2 family with a digest length of 256 bits). SHA-256 hashes used properly can confirm both file integrity and authenticity.
