Encryption segments are bound to their location and cannot be reordered or moved. Decryption allows partial ciphertext processing. The recommended key type is AES128_GCM_HKDF_1MB. Streaming AEAD offers CCA2 security, at least 80-bit authentication strength, and can encrypt at least 2^64 messages with a total of 2^51 bytes. Re-encrypting the whole stream is needed to modify the ciphertext.\n"]]
