Function Block CRYPT_CRC32

The Function Block CRYPT_CRC32 calculates the polynomial CRC32 value of a string.

Calculated is the cyclic redundant polynomial checksum with a length of 32-Bit for the input. This is usually used for integrity checking of transmitted data.

Warning: Since the Integer data type from Antcas Control is signed, many checksums on 32bit platforms result in negative integer values. However, all CRC32 results are positive integers in 64bit installations.

Input

The value for calculating the checksum is passed at the input. This can be passed as a number or as a string.

Output

The output provides the checksum of the value from the input as an integer.
