Verifies that the signature is valid for the message's content using the specified key.
public bool VerifyDetached (System.Security.Cryptography.AsymmetricAlgorithm key, byte[] detachedContent, byte[]? associatedData = default);
member this.VerifyDetached : System.Security.Cryptography.AsymmetricAlgorithm * byte[] * byte[] -> bool
Public Function VerifyDetached (key As AsymmetricAlgorithm, detachedContent As Byte(), Optional associatedData As Byte() = Nothing) As Boolean
Parameters
The private key used to sign the content.
- detachedContent
- Byte[]
The content that was previously signed.
- associatedData
- Byte[]
The extra data associated with the signature, which must match the value provided during signing.
Returns
true
if the signature is valid; otherwise, false
.
Exceptions
key
or detachedContent
is null
.
key
is of an unsupported type.
The content is embedded on the associated message, use an overload that uses embedded content.
ProtectedHeaders does not have a value for the Algorithm header.
-or-
The algorithm protected header was incorrectly formatted.
-or-
The algorithm protected header was not one of the values supported by this implementation.
-or-
The algorithm protected header doesn't match with the algorithms supported by the specified key
.
