Parameters

Return Value

Type: System.Boolean

Remarks

Any IssuingAuthority in IssuingAuthorities that contains both the base64EncodedKey in SymmetricKeys and issuer in Issuers will be considered a valid pair.

Warning

If you choose to override this method please be aware of the need to use the appropriate case when comparing keys. Symmetric keys are case sensitive. Comparing keys as case insensitive could lead to security issues.
