MD5CryptoServiceProvider Class (System.Security.Cryptography) | Microsoft Learn

Caution

Derived cryptographic types are obsolete. Use the Create method on the base type instead.

Computes the MD5 hash value for the input data using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.

Attributes

Hash functions map binary strings of an arbitrary length to small binary strings of a fixed length. A cryptographic hash function has the property that it is computationally infeasible to find two distinct inputs that hash to the same value; that is, hashes of two sets of data should match if the corresponding data also matches. Small changes to the data result in large, unpredictable changes in the hash.

The hash size for the MD5CryptoServiceProvider class is 128 bits.

The ComputeHash methods of the MD5CryptoServiceProvider class return the hash as an array of 16 bytes. Note that some MD5 implementations produce a 32-character, hexadecimal-formatted hash. To interoperate with such implementations, format the return value of the ComputeHash methods as a hexadecimal value.

Releases all resources used by the HashAlgorithm class.

Computes the hash value for the specified region of the specified byte array.

Computes the hash value for the specified byte array.

Computes the hash value for the specified Stream object.

Asynchronously computes the hash value for the specified Stream object.

Releases all resources used by the current instance of the HashAlgorithm class.

Releases the unmanaged resources used by the HashAlgorithm and optionally releases the managed resources.

Determines whether the specified object is equal to the current object.

Releases the resources that are being used by the MD5CryptoServiceProvider.

Serves as the default hash function.

Gets the Type of the current instance.

When overridden in a derived class, routes data written to the object into the hash algorithm for computing the hash.

Routes data written to the object into the hash algorithm for computing the hash.

When overridden in a derived class, finalizes the hash computation after the last data is processed by the cryptographic hash algorithm.

Initializes an instance of MD5CryptoServiceProvider.

Creates a shallow copy of the current Object.

Returns a string that represents the current object.

Computes the hash value for the specified region of the input byte array and copies the specified region of the input byte array to the specified region of the output byte array.

Computes the hash value for the specified region of the specified byte array.

Attempts to compute the hash value for the specified byte array.

Attempts to finalize the hash computation after the last data is processed by the hash algorithm.
