Luhn algorithm - Wikipedia

The algorithm appeared in a United States Patent [1] for a simple, hand-held, mechanical device for computing the checksum. The device took the mod 10 sum by mechanical means. The substitution digits, that is, the results of the double and reduce procedure, were not produced mechanically.

Because PHP's integer type is signed many crc32 checksums will result in negative integers on 32bit platforms. On 64bit installations all crc32() results will be positive integers though.. So you need to use the "%u" formatter of sprintf() or printf() to get the string representation of the unsigned crc32() checksum in decimal format. rainbow quaker tiles

"WebNov 6, 2024 · The MD5 is considered to be cryptographically broken and can be attacked by an average computer. In terms of speed, the MD5 is slightly faster than SHA-2. Therefore, the MD5 is often used as a checksum for verifying files integrity. To sum up, in most cases, SHA-2 will do better than MD5. " - Algoritmo checksum
