AEADkirjastoja

AEADkirjastoja refers to a collection of libraries or frameworks designed to implement Authenticated Encryption with Associated Data (AEAD) algorithms. AEAD is a symmetric encryption mode that provides both confidentiality and integrity for data, along with authentication for associated unencrypted data. This means it not only encrypts the message but also ensures that the message has not been tampered with and that any additional data provided alongside the message (like headers) is also authenticated.

Libraries implementing AEAD algorithms typically offer interfaces for key generation, nonce generation, encryption, and decryption. Popular AEAD algorithms include AES-GCM (Galois/Counter Mode), ChaCha20-Poly1305, and XChaCha20-Poly1305. These libraries abstract away the complexities of cryptographic operations, making it easier for developers to integrate robust security features into their applications.

The primary benefit of using AEAD libraries is the reduced risk of implementation errors, which are a common source of vulnerabilities in cryptographic systems. By providing well-tested and standardized implementations, these libraries help developers avoid common pitfalls associated with manual cryptographic construction. They are widely used in network protocols, secure storage, and communication systems where both data secrecy and integrity are paramount.
