class System.Security.Cryptography.Rfc2898DeriveBytes
Assembly: System.Security.Cryptography
Inheritance: object → DeriveBytes → Rfc2898DeriveBytes
Implements password-based key derivation functionality, PBKDF2, by using a pseudo-random number generator based on <see cref="T:System.Security.Cryptography.HMACSHA1" /> .
Properties
public
HashAlgorithmName
HashAlgorithm
Gets the hash algorithm used for byte derivation.
public
int
IterationCount
Gets or sets the number of iterations for the operation.
public
byte[]
Salt
Gets or sets the key salt value for the operation.
Methods
public
byte[]
CryptDeriveKey(string algname,
string alghashname,
int keySize,
byte[] rgbIV)
algname
The algorithm name for which to derive the key.
alghashname
The hash algorithm name to use to derive the key.
keySize
The size of the key, in bits, to derive.
rgbIV
The initialization vector (IV) to use to derive the key.
Returns The derived key.
Derives a cryptographic key from the <see cref="T:System.Security.Cryptography.Rfc2898DeriveBytes" /> object.
protected
void
Dispose(bool disposing)
disposing
<see langword="true" /> to release both managed and unmanaged resources; <see langword="false" /> to release only unmanaged resources.
Releases the unmanaged resources used by the <see cref="T:System.Security.Cryptography.Rfc2898DeriveBytes" /> class and optionally releases the managed resources.
public
byte[]
GetBytes(int cb)
cb
The number of pseudo-random key bytes to generate.
Returns A byte array filled with pseudo-random key bytes.
Returns the pseudo-random key for this object.
public
void
Reset()
Resets the state of the operation.
When overridden in a derived class, releases all resources used by the current instance of the <see cref="T:System.Security.Cryptography.DeriveBytes" /> class.
