Package tea implements the TEA algorithm, as defined in Needham and Wheeler's 1994 technical report, “TEA, a Tiny Encryption Algorithm”. See http://www.cix.co.uk/~klockstone/tea.pdf for details.
TEA is a legacy cipher and its short block size makes it vulnerable to birthday bound attacks (see https://sweet32.info). It should only be used where compatibility with legacy systems, not security, is the goal.
Deprecated: any new system should use AES (from crypto/aes, if necessary in an AEAD mode like crypto/cipher.NewGCM) or XChaCha20-Poly1305 (from golang.org/x/crypto/chacha20poly1305).
const ( // BlockSize is the size of a TEA block, in bytes. BlockSize = 8 // KeySize is the size of a TEA key, in bytes. KeySize = 16 )
NewCipher returns an instance of the TEA cipher with the standard number of rounds. The key argument must be 16 bytes long.
NewCipherWithRounds returns an instance of the TEA cipher with a given number of rounds, which must be even. The key argument must be 16 bytes long.
