Collection of symmetric Key Wrapping Functions (KW) written in pure Rust.
"Key Wrapping" describes symmetric encryption algorithms designed for encrypting cryptographic key material under another symmetric key, known as a "Key-Encrypting-Key" (KEK).
They're intended for applications such as protecting keys while in untrusted storage or transmitting keys over untrusted communications networks.
