/**
 * KeyLike are runtime-specific classes representing asymmetric keys or symmetric secrets. These are
 * instances of {@link https://developer.mozilla.org/en-US/docs/Web/API/CryptoKey CryptoKey} and
 * additionally {@link https://nodejs.org/api/crypto.html#class-keyobject KeyObject} in Node.js
 * runtime.
 * {@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array Uint8Array}
 * instances are also accepted as symmetric secret representation only.
 *
 * [Key Import Functions](../modules/key_import.md) can be used to import PEM, or JWK formatted
 * asymmetric keys and certificates to these runtime-specific representations.
 *
 * In Node.js the {@link https://nodejs.org/api/buffer.html#buffer Buffer} class is a subclass of
 * Uint8Array and so Buffer can be provided for symmetric secrets as well.
 *
 * {@link https://nodejs.org/api/crypto.html#class-keyobject KeyObject} is a representation of a
 * key/secret available in the Node.js runtime. In addition to the import functions of this library
 * you may use the runtime APIs
 * {@link https://nodejs.org/api/crypto.html#cryptocreatepublickeykey crypto.createPublicKey},
 * {@link https://nodejs.org/api/crypto.html#cryptocreateprivatekeykey crypto.createPrivateKey}, and
 * {@link https://nodejs.org/api/crypto.html#cryptocreatesecretkeykey-encoding crypto.createSecretKey}
 * to obtain a `KeyObject` from your existing key material.
 *
 * {@link https://developer.mozilla.org/en-US/docs/Web/API/CryptoKey CryptoKey} is a representation
 * of a key/secret available in the Browser and Web-interoperable runtimes. In addition to the
 * import functions of this library you may use the
 * {@link https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/importKey SubtleCrypto.importKey}
 * API to obtain a CryptoKey from your existing key material.
