Enumeration: STORAGE_TYPE

Enum representing cryptographic storage types for sensitive data.

Security Level Categories:

  1. High Security (Biometric Authentication Required):
  • AES_GCM: For sensitive local data (passwords, personal info)
  • RSA: For asymmetric operations (signatures, key exchange)
  1. Medium Security (No Authentication):
  • AES_GCM_NO_AUTH: For app-level secrets and cached data
  1. Legacy/Deprecated:
  • AES_CBC: Outdated, use AES_GCM_NO_AUTH instead
  • FB: Archived Facebook Conceal implementation

Platform​

Android

Enumeration Members​

AES​

AES: "KeystoreAES"

Encryptions without human interaction.

Deprecated​

Use AES_GCM_NO_AUTH instead.

Defined in​

enums.ts:126

AES_CBC​

AES_CBC: "KeystoreAESCBC"

AES encryption in CBC (Cipher Block Chaining) mode. Provides data confidentiality without authentication.

Deprecated​

Use AES_GCM_NO_AUTH instead.

Defined in​

enums.ts:132

AES_GCM​

AES_GCM: "KeystoreAESGCM"

AES-GCM encryption with biometric authentication. Requires user authentication for both encryption and decryption operations.

Defined in​

enums.ts:142

AES_GCM_NO_AUTH​

AES_GCM_NO_AUTH: "KeystoreAESGCM_NoAuth"

AES encryption in GCM (Galois/Counter Mode). Provides both data confidentiality and authentication.

Defined in​

enums.ts:137

FB​

FB: "FacebookConceal"

Facebook compatibility cipher.

Deprecated​

Facebook Conceal was deprecated and archived in Mar 3, 2020. https://github.com/facebookarchive/conceal

Defined in​

enums.ts:122

RSA​

RSA: "KeystoreRSAECB"

RSA encryption with biometric authentication. Uses asymmetric encryption and requires biometric authentication.

Defined in​

enums.ts:147
