The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\nstatic\n\n\nclass\nFingerprintManagerCompat.CryptoObject\n`\n\n\n`\n\nextends Object\n\n\n`\n\n`\n\n\n`\n\n|---|-------------------------------------------------------------------------------|\n| java.lang.Object ||\n| ↳ | android.support.v4.hardware.fingerprint.FingerprintManagerCompat.CryptoObject |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nA wrapper class for the crypto objects supported by FingerprintManager.
