IDSCryptoConfiguration class
AES-256-CBC Encryption/Decryption core utility using PBKDF2 key derivation.
This class is responsible for generating a secure encryption key based on a password and salt using PBKDF2 with HMAC-SHA256. It also includes helper methods to convert between byte arrays and hex strings.
Constructors
- IDSCryptoConfiguration({required String password, String salt = 'salt', int iterations = 10000, int keyLength = 32, int ivLength = 16})
- Creates a new IDSCryptoConfiguration instance with customizable parameters.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- iterations → int
-
Number of iterations to apply during key derivation.
final
- ivLength → int
-
Initialization Vector (IV) length in bytes (typically 16).
final
- keyLength → int
-
Length of the derived key in bytes (e.g., 32 for AES-256).
final
- password → String
-
Password used for key derivation.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- salt → String
-
Salt used with the password in PBKDF2 (should be random in production).
