Compute a hash for the first 100 bytes of a file:

Equivalently:

Compute a hash for the last 100 bytes:

Equivalently:

Compute a hash for bytes 100 through 200:

Compute a hash for all bytes except the first 100 or the last 100:

Compute the hash for byte 100 only:

Compute a hash for no bytes:

Compute the hashes of several files:

Find the hash for a complete file as well as several subsets of it:

Create a CloudObject :

Find the hash of the data contained in the CloudObject :

By default, MD5 hash of the full range is calculated:

For hashing, the data from the CloudObject is represented as a string including the newline:

The same hash using the sequence of bytes:

Open a binary stream:

Compute its hash:

The same result is given independently of the current stream position:

Close the stream:

Create an empty file and cloud object:

Put the same content in the file and cloud object:

Also open a stream pointing at the file:

The hashes of all three objects are the same:

Close the stream:

Compare different hash codes:

512-bit SHA code given as an integer:

512-bit SHA code given as a decimal string, including leading zeros:

Compare the different string representations of a hash:

The double SHA code of the first 50 bytes of a file, given as a ByteArray :

The byte array contains the 256 bits of the result:
