 **Supported Key Types**
 
-The [`generateKeyPair`](#generatekeypairtype-bits-callback), [`marshalPublicKey`](#marshalpublickeykey-type-callback), and [`marshalPrivateKey`](#marshalprivatekeykey-type) functions accept a string `type` argument.
+The [`generateKeyPair`](#cryptokeysgeneratekeypairtype-bits-callback), [`marshalPublicKey`](#cryptokeysmarshalpublickeykey-type-callback), and [`marshalPrivateKey`](#cryptokeysmarshalprivatekeykey-type) functions accept a string `type` argument.
 
 Currently the `'RSA'` and `'ed25519'` types are supported, although ed25519 keys support only signing and verification of messages.  For encryption / decryption support, RSA keys should be used.
