Crypto Tokens provide access to the keys and cryptography operations. Each Signer is typically configured with a reference to a Crypto Worker having a Crypto Token configured.
Available SignServer Crypto Tokens:
A worker can contain a crypto token as a component by defining which crypto token implementation to use with the CRYPTOTOKEN_IMPLEMENTATION_CLASS property and then add any other properties needed by that implementation.
A worker with the sole purpose of holding a crypto token is called a Crypto Worker. Then other workers that need a crypto token can instead simply refer to a crypto token in the other worker by specifying the (crypto) worker name in a CRYPTOTOKEN property.
