- hash
- ReadOnlySpan<Byte>
The hash to verify.
- signature
- ReadOnlySpan<Byte>
The signature to verify.
- hashAlgorithmOid
- String
The OID of the hash algorithm used to create the hash.
- context
- ReadOnlySpan<Byte>
The context value which was provided during signing.
The default value is an empty buffer.
Returns
true if the signature validates the hash; otherwise, false.
- Attributes
Exceptions
hashAlgorithmOid is null.
context has a Length in excess of 255 bytes.
This instance has been disposed.
hashAlgorithmOid is not a well-formed OID.
-or-
hashAlgorithmOid is a well-known algorithm and hash does not have the expected length.
-or-
An error occurred while verifying the hash.

- hash
- Byte[]
The hash to verify.

The signature to verify.
- hashAlgorithmOid
- String
The OID of the hash algorithm used to create the hash.
Returns
true if the signature validates the hash; otherwise, false.
