Definition

Namespace:

Microsoft.IdentityModel.Tokens

Assembly:

Microsoft.IdentityModel.Tokens.dll

Package:

Microsoft.IdentityModel.Tokens v7.5.1

Overloads

Verify(Byte[], Byte[])	Verifies that a signature created over the 'input' matches the signature. Using SymmetricSecurityKey and 'algorithm' passed to SymmetricSignatureProvider(SecurityKey, String).
Verify(Byte[], Byte[], Int32)	Verifies that a signature created over the 'input' matches the signature. Using SymmetricSecurityKey and 'algorithm' passed to SymmetricSignatureProvider(SecurityKey, String).
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 a signature created over the 'input' matches the signature. Using SymmetricSecurityKey and 'algorithm' passed to SymmetricSignatureProvider(SecurityKey, String).

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 verify.

signature

Byte[]

signature to compare against.

Returns

Boolean

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

Exceptions

ArgumentNullException

'signature' is null.

ArgumentException

'signature.Length' == 0.

ObjectDisposedException

Dispose(Boolean) has been called.

InvalidOperationException

If the internal KeyedHashAlgorithm is null. This can occur if a derived type deletes it or does not create it.

Remarks

Verify is thread safe.

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

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

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

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

Public Function Verify (input As Byte(), signature As Byte(), length As Integer) As Boolean

Parameters

input

Byte[]

The bytes to verify.

signature

Byte[]

signature to compare against.

length

Int32

number of bytes of signature to use.

Returns

Boolean

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

Exceptions

ArgumentNullException

'signature' is null.

ArgumentException

'length < 1'

ObjectDisposedException

Dispose(Boolean) has been called.

InvalidOperationException

If the internal KeyedHashAlgorithm is null. This can occur if a derived type deletes it or does not create it.

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.
