# CrossmintMetamaskDecrypt

Class for decrypting verifiable credentials encrypted with the `VerifiableCredentialEncryptionType.CROSSMINT_RECOVERABLE` encryption type using Metamask.

This class uses Metamask to prompt the user to sign a message to decrypt the credential.
If you want to use a different signature method, refer to the `CrossmintDecrypt` class.
To use the Crossmint decrypt endpoint, an API key with the `credentials.decrypt` scope must be provided.
