Enables secure storage of sensitive data in applications by leveraging native security APIs. Supports symmetric and asymmetric key generation for data protection, using AES and RSA encryption algorithms. Provides seamless integration into applications with both synchronous and asynchronous methods.
v1.0.0
Kassaforte enables secure storage of sensitive data in Compose Multiplatform applications and on the backend by
leveraging
each platform’s native security APIs. It further supports the generation and usage of symmetric and asymmetric keys
to
ensure data protection
Algorithm used to encrypt and decrypt data the following block modes:
CBC - Cipher Block Chaining where each block of plaintext is XORed with the previous ciphertext block before
being encrypted. Requires an initialization vector (IV) of the block sizeAlgorithm used to sign and verify messages with the following digests:
SHA1SHA256SHA384SHA512The keys are generated with the KeyGenerator API and securely stored inside the Keystore provided by Android. The keys are used by the Cipher to encrypt or decrypt the data
The keys are generated with the SecRandomCopyBytes API and securely stored inside the Keychain provided by iOS and macOS operating systems. The keys are used by korlibs-crypto library to encrypt or decrypt the data
Like on Android the keys are generated with
the KeyGenerator API, but
the keys are securely stored using the java-keyring library.
The keys are used by the Cipher to encrypt or
decrypt the data
The keys are generated with the SubtleCrypto API and
securely stored into application's IndexedDB.
The keys are used by the SubtleCrypto to encrypt or decrypt the data
The supported asymmetric algorithms to generate and then use the keys are the following:
RSA asymmetric encryption algorithm based on the hardness of factoring large integers. Are supported two padding
modes:
PKCS#1 RSA signature scheme with PKCS#1 v1.5 padding (on the web just signing and verifying only)RSA_OAEP RSA encryption using OAEP paddingThe keys are generated with the KeyPairGenerator API and securely stored inside the Keystore provided by Android. The keys are used by the Cipher to encrypt or decrypt the data
The keys are generated with the SecKeyCreateRandomKey API and securely stored inside the Keychain provided by iOS and macOS operating systems. The keys are used by security methods provided by Apple to encrypt or decrypt the data
Like on Android the keys are generated with
the KeyPairGenerator API, but
the keys are securely stored using the java-keyring library.
The keys are used by the Cipher to encrypt or
decrypt the data
The keys are generated with the SubtleCrypto API and
securely stored into application's IndexedDB.

}
Using the services you can generate and then use symmetric and asymmetric keys

and
use keys, as well as how to correctly use the Kassaforte API.

On Android the data are stored in
the SharedPreferences, encrypting the
data before storing it
On iOS and native macOS the data are stored in
the Keychain
On JVM to store the data are leveraged the native APIs provided by the different OSs:
Windows the data are stored in
the Windows CredentialsLinux the data are stored using the implementation of
the DBus Secret Service based
on the desktop environment between
GNOME or KDEMacOs the data are stored in
the KeychainThis target uses the java-keyring library under the hood
On Web the data are stored in
the LocalStorage, encrypting the data before
storing it
CTR - Counter mode turns a block cipher into a stream cipher by encrypting successive values of a counter and
XORing them with the plaintext. Provides parallelizable encryption and decryptionGCM - Galois/Counter Mode it is based on CTR mode for encryption, but also provides authentication (AEAD)
using Galois field multiplication.
Requires a nonce, typically 12 bytes for efficiency (on Apple at the moment is not supported)EC| Method | Description |
