Miscellaneous APIs

警告

Types that implement any of the following interfaces should be thread-safe for multiple callers.

ISecret

The ISecret interface represents a secret value, such as cryptographic key material. It contains the following API surface.

• Length : int

• Dispose() : void

• WriteSecretIntoBuffer(ArraySegment buffer) : void

The WriteSecretIntoBuffer method populates the supplied buffer with the raw secret value. The reason this API takes the buffer as a parameter rather than returning a byte[] directly is that this gives the caller the opportunity to pin the buffer object, limiting secret exposure to the managed garbage collector.

The Secret type is a concrete implementation of ISecret where the secret value is stored in in-process memory. On Windows platforms, the secret value is encrypted via CryptProtectMemory.
