CryptoTokenKit framework provides access to cryptographic tokens. Tokens are physical devices built in to the system, located on attached hardware (like a smart card), or accessible through a network connection. Tokens store cryptographic objects like keys and certificates.
You use the CryptoTokenKit framework to easily access cryptographic tokens. Tokens are physical devices built in to the system, located on attached hardware (like a smart card), or accessible through a network connection. Tokens store cryptographic objects like keys and certificates. They also may perform operations—for example, encryption or digital signature verification—using these objects. You use the framework to work with a token's assets as if they were part of your system, even though they remain secured by the token.
