AsymmetricSignatureProvider.Verify Method

Definition

Namespace:

Microsoft.IdentityModel.Tokens

Assembly:

Microsoft.IdentityModel.Tokens.dll

Package:

Microsoft.IdentityModel.Tokens v7.5.1

Overloads

Verify(Byte[], Byte[])	Verifies that the signature over input using the SecurityKey and Algorithm specified by this SignatureProvider are consistent.
Verify(Byte[], Int32, Int32, Byte[], Int32, Int32)	Verifies that a signature created over the 'input' matches the signature. Using SecurityKey and 'algorithm' passed to SignatureProvider(SecurityKey, String).

Verify(Byte[], Byte[])

Verifies that the signature over input using the SecurityKey and Algorithm specified by this SignatureProvider are consistent.

public override bool Verify (byte[] input, byte[] signature);

override this.Verify : byte[] * byte[] -> bool

Public Overrides Function Verify (input As Byte(), signature As Byte()) As Boolean

Parameters

input

Byte[]

The bytes to generate the signature over.

signature

Byte[]

The value to verify against.

Returns

Boolean

true if signature matches, false otherwise.

Exceptions

ArgumentNullException

signature is null or has length == 0.

ObjectDisposedException

If Dispose(Boolean) has been called.

Remarks

Verify is thread safe.

Verify(Byte[], Int32, Int32, Byte[], Int32, Int32)

Verifies that a signature created over the 'input' matches the signature. Using SecurityKey and 'algorithm' passed to SignatureProvider(SecurityKey, String).

public override bool Verify (byte[] input, int inputOffset, int inputLength, byte[] signature, int signatureOffset, int signatureLength);

override this.Verify : byte[] * int * int * byte[] * int * int -> bool

Public Overrides Function Verify (input As Byte(), inputOffset As Integer, inputLength As Integer, signature As Byte(), signatureOffset As Integer, signatureLength As Integer) As Boolean

Parameters

input

Byte[]

The bytes to verify.

inputOffset

Int32

offset in to input bytes to caculate hash.

inputLength

Int32

number of bytes of signature to use.

signature

Byte[]

signature to compare against.

signatureOffset

Int32

offset into signature array.

signatureLength

Int32

how many bytes to verfiy.

Returns

Boolean

true if computed signature matches the signature parameter, false otherwise.
