Overview ¶
Package keys contains various encryption KeyHandler implementations.
Index ¶
Constants ¶
const ( // TokenTypeKMS is KMS assisted encryption token. TokenTypeKMS = "sideroKMS" // TokenTypeTPM is TPM assisted encryption token. TokenTypeTPM = "talos-tpm2" )
Variables ¶
var ErrTokenInvalid = errors.New("invalid token")
ErrTokenInvalid is returned by the keys handler if the supplied token is not valid.
