SHA1OpenNURBS

SHA1HashAlgorithm
public sealed class SHA1OpenNURBS : SHA1
Provides the OpenNURBS implementation of SHA1.

This class is provided only with the purpose of hashing. It is not meant to be used for any cryptographic purpose.

Constructors

SHA1OpenNURBS

#Since v6.0
public SHA1OpenNURBS()
Constructs a new instance of the SHA1 algorithm.

Finalizer

~SHA1OpenNURBS

#
~SHA1OpenNURBS()
Instructs the runtime to reclaim unmanaged resources if the developer forgot to call Dispose().

Methods

Dispose

#
protected override void Dispose(bool disposing)
Reclaims unmanaged resources used by this instance, and invalidates the instance. After calling this method, all other methods will always call ObjectDisposedException.
Parameters:
disposing (bool)true if the class user called Dispose.
Overrides: HashAlgorithm.Dispose

FileSystemPathHash

#
public static byte[] FileSystemPathHash(string path, bool? ignoreCase = null)
Computes the SHA1 hash of a file system path, converted to UTF8.

These file system paths have identical values of FileSystemPathHash():

/x/y/z/name.ext

\x\y\z\name.ext

/x//y//z/name.ext

/x/y/a/b/c/../../../z/name.ext

/X/Y/Z/NAME.EXT (When ignoreCase is true)

Parameters:
path (string)A non-null path string.
ignoreCase (bool? = null)If case should be ignored. If this is null or unspecified, the operating system default is used.
Returns: A 20-byte long SHA1 hash.
Exceptions:
ArgumentNullExceptionWhen input is null.

HashCore

#
protected override void HashCore(byte[] array, int start, int length)
Advances the hash by an input array.
Parameters:
array (byte[])The array.
start (int)The start of the data to consider in the array.
length (int)The used data length on the array.
Overrides: HashAlgorithm.HashCore

HashFinal

#
protected override byte[] HashFinal()
Returns the currently computed hash.
Returns: The final hash.
Overrides: HashAlgorithm.HashFinal

Initialize

#Since v6.0
public override void Initialize()
Resets this instance of the algorithm, so that it can be used again. It is not required to call this method after creation.
Overrides: HashAlgorithm.Initialize

StringHash

#Since v6.0
public static byte[] StringHash(string input)
Computes the SHA1 hash of a string, converted to UTF8.
Parameters:
input (string)
Returns: A 20-byte long SHA1 hash.
Exceptions:
ArgumentNullExceptionWhen input is null.
