<binary> The binary string to calculate the hash value for.

Return Value

Success: Returns the hash value as an integer.
Failure: Returns 0.


The BinaryHash32 and BinaryHash64 functions provide a simple and generic way to calculate hash values for binary strings. These hash functions utilize a standard hashing algorithm that takes the input binary string and produces a hash value of either 32 or 64 bits in size, respectively. While these hash functions do not offer any specific optimizations or unique features, they can still be useful for basic hash calculations, such as generating hash codes for data comparison or implementing hash-based data structures. It's important to note that these hash functions are not intended for cryptographic purposes but rather for general-purpose hashing needs.

In addition to providing a simple and generic hash calculation, the BinaryHash32 and BinaryHash64 functions offer a useful feature for detecting changes in binary data. Since the hash value is calculated based on the content of the binary string, any change in the input will result in a different hash value. This property makes these hash functions suitable for checking the integrity or detecting modifications in binary data. By comparing the hash value of a binary string before and after some operation, you can quickly determine if any changes have occurred. It's important to note that while these hash functions can detect changes, they do not provide any specific information about the nature or location of the changes.

Example of usage:

my $a = Bin("Hello World!");
say BinaryHash32($a);
say BinaryHash64($a);

// 21676401
// 21676401
