Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

public override ICryptoTransform CreateDecryptor (
	byte[] rgbKey,
	byte[] rgbIV
)
public ICryptoTransform CreateDecryptor (
	byte[] rgbKey, 
	byte[] rgbIV
)
public override function CreateDecryptor (
	rgbKey : byte[], 
	rgbIV : byte[]
) : ICryptoTransform

Parameters
