  - verifyChecksum
```
 final Unit verifyChecksum(String expected, String actual, ChecksumAlgorithm checksumAlgorithm)
```
  - checksumFor
```
 final String checksumFor(Path path, ChecksumAlgorithm algorithm)
```
    Calculate a checksum for the given path and algorithm.
    
    Parameters:
    
    path - Path containing the bytes to generate the checksum for
    
    algorithm - algorithm to use
    
    Returns:
    
    the checksum
  - checksumMultipart
```
 final String checksumMultipart(List<Path> paths, ChecksumAlgorithm algorithm)
```
    Calculates the checksum for a list of paths. For multipart uploads, AWS takes the checksum of all parts, concatenates them, and then takes the checksum again. Then, they add a hyphen and the number of parts used to calculate the checksum. API
