WrappingScheme

Represents different methods for securely wrapping (encrypting) cryptographic keys. Key wrapping is a crucial operation in cryptography, used to securely transmit or store sensitive key material.

Properties

AES_KEY_WRAP

readonly static AES_KEY_WRAP: "AesKeyWrapScheme" = "AesKeyWrapScheme"

Constant representing the AES Key Wrap scheme.

This scheme uses the AES algorithm to wrap and unwrap keys directly. The key material is encrypted using an AES key, providing confidentiality and integrity for the wrapped key.

ECDH_AES_KEY_WRAP

readonly static ECDH_AES_KEY_WRAP: "EcdhAesKeyWrapScheme" = "EcdhAesKeyWrapScheme"

Constant representing the ECDH AES Key Wrap scheme.

This scheme utilizes Elliptic Curve Diffie-Hellman (ECDH) for key exchange, combined with AES for key wrapping. The wrapping process for this scheme:

1. An ECDH key pair is used to derive a shared secret, which is then used as an AES key;
2. Use the AES key to wrap the key material. This method ensures that both parties involved in the key exchange can securely communicate and unwrap the key material using the derived AES key.

RSA_AES_KEY_WRAP

readonly static RSA_AES_KEY_WRAP: "RsaAesKeyWrapScheme" = "RsaAesKeyWrapScheme"

Constant representing the RSA AES Key Wrap scheme.

This scheme combines the RSA and AES algorithms to securely wrap and unwrap keys. The wrapping process involves:

1. Generating a temporary AES key;
2. Encrypting it with the RSA public key;
3. Using this AES key to encrypt the key material. The final wrapped key consists of both the RSA-encrypted AES key and the AES-encrypted key material. This ensures that only the holder of the corresponding RSA private key can decrypt and retrieve the AES key, and subsequently, the key material.
