The CryptoKeyManager component provides a simple way to load, generate and manage generic crypto keys.

Syntax

TsbiCryptoKeyManager

Remarks

CryptoKeyManager allows you to load, save, generate, import, and export low-level crypto keys. One example of such keys are raw RSA keys stored in PKCS1 format or AES256 keys. CryptoKeyManager supports asymmetric, symmetric, and HMAC keys.

CryptoKeyManager is a typical companion for low-level cryptography classes, such as PublicKeyCrypto, SymmetricCrypto, and HashFunction. It can also be used to provide external key material to certificate objects, and to derive cryptographic keys from passwords.

Use ImportBytes or ImportFromFile method to load the key material from a buffer or file. Use ImportFromCert (and remember to assign the certificate object to the Certificate property before calling it) to import a key from an X.509 certificate. Once loaded, the key will be available in the Key property.

To generate a new key or keypair use Generate method. You can export the generated key using ExportBytes or ExportToFile method. You can attach the generated or loaded key to an external certificate object using the ExportToCert method.

Note: CryptoKeyManager can only work with one cryptographic key at a time. Use CryptoKeyStorage to access media containing more than one key.
