Package Usage: go: github.com/secure-io/siv-go

Package siv implements the Synthetic Initialization Vector (SIV) authenticated encryption scheme specified in RFC 5297. It also implements AES-GCM-SIV as misuse-resistant version of AES-GCM as proposed by the RFC-draft [1]. AES-GCM-SIV is a misuse-resistant AEAD scheme using AES-{128/256} for message privacy and a polynomial authenticator (POLYVAL) for message integrity. In contrast to other AEAD schemes - like AES-GCM - AES-GCM-SIV provides message integrity and message privacy (w.r.t the security of deterministic encryption) even if the nonce is reused. AES-GCM-SIV creates a ciphertext which is 16 bytes longer than the plaintext. The ciphertext consists of the encrypted plaintext followed by the (16 byte) authentication tag. For more details see [1]. AES-SIV-CMAC is a misuse-resistant AEAD scheme using AES-{128/192/256} for message privacy and integrity. In contrast to other AEAD schemes - like AES-GCM - AES-SIV-CMAC provides message integrity and message privacy (w.r.t the security of deterministic encryption) even if the nonce is reused or omitted at all. AES-SIV-CMAC creates a ciphertext which is 16 bytes longer than the plaintext. The ciphertext consists of the authentication tag (16 bytes) followed by the encrypted plaintext. For more details see [2]. Given the same plaintext and additional data a deterministic AEAD produces always the same ciphertext. Therefore it is not semantically secure. [3] However, any deterministic AEAD implemented by this package accepts a non-nil nonce making the encryption probabilistic. A deterministic AEAD which can be turned into a probabilistic AEAD using a nonce value is called misuse-resistant AEAD.
