That way, you + * can encrypt at most \c 2**96 messages of up to \c 2**32 blocks + * each with the same key. + * + * The per-message nonce (or information sufficient to reconstruct + * it) needs to be communicated with the ciphertext and must be + * unique. The recommended way to ensure uniqueness is to use a + * message counter. An alternative is to generate random nonces, + * but this limits the number of messages that can be securely + * encrypted: for example, with 96-bit random nonces, you should + * not encrypt more than 2**32 messages with the same key. + * + * Note that for both stategies, sizes are measured in blocks and + * that a CAMELLIA block is \c 16 Bytes. + * + * \warning Upon return, \p stream_block contains sensitive data.

No explicit IV is contained + * in an encrypted record. The IV for the first record is extracted + * at key extraction time. In contrast, for TLS 1.1 and 1.2, no + * IV is generated at key extraction time, but every encrypted + * record is explicitly prefixed by the IV with which it was encrypted. + * - AEAD transformations ([D]TLS versions >= 1.2 only) + * These come in two fundamentally different versions, the first one + * used in TLS 1.2, excluding ChaChaPoly ciphersuites, and the second + * one used for ChaChaPoly ciphersuites in TLS 1.2 as well as for TLS 1.3. + * In the first transformation, the IV to be used for a record is obtained + * as the concatenation of an explicit, static 4-byte IV and the 8-byte + * record sequence number, and explicitly prepending this sequence number + * to the encrypted record. In contrast, in the second transformation + * the IV is obtained by XOR'ing a static IV obtained at key extraction + * time with the 8-byte record sequence number, without prepending the + * latter to the encrypted record. + * + * Additionally, DTLS 1.2 + CID as well as TLS 1.3 use an inner plaintext + * which allows to add flexible length padding and to hide a record's true + * content type. + * + * In addition to type and version, the following parameters are relevant: + * - The symmetric cipher algorithm to be used. + * - The (static) encryption/decryption keys for the cipher. + * - For stream/CBC, the type of message digest to be used. + * - For stream/CBC, (static) encryption/decryption keys for the digest. + * - For AEAD transformations, the size (potentially 0) of an explicit, + * random initialization vector placed in encrypted records. + * - For some transformations (currently AEAD and CBC in SSL3 and TLS 1.0) + * an implicit IV. It may be static (e.g. AEAD) or dynamic (e.g. CBC) + * and (if present) is combined with the explicit IV in a transformation- + * dependent way (e.g. appending in TLS 1.2 and XOR'ing in TLS 1.3). + * - For stream/CBC, a flag determining the order of encryption and MAC. + * - The details of the transformation depend on the SSL/TLS version. + * - The length of the authentication tag. + * + * Note: Except for CBC in SSL3 and TLS 1.0, these parameters are + * constant across multiple encryption/decryption operations. + * For CBC, the implicit IV needs to be updated after each + * operation. + * + * The struct below refines this abstract view as follows: + * - The cipher underlying the transformation is managed in + * cipher contexts cipher_ctx_{enc/dec}, which must have the + * same cipher type. The mode of these cipher contexts determines + * the type of the transformation in the sense above: e.g., if + * the type is MBEDTLS_CIPHER_AES_256_CBC resp. MBEDTLS_CIPHER_AES_192_GCM + * then the transformation has type CBC resp. AEAD. + * - The cipher keys are never stored explicitly but + * are maintained within cipher_ctx_{enc/dec}. + * - For stream/CBC transformations, the message digest contexts + * used for the MAC's are stored in md_ctx_{enc/dec}. These contexts + * are unused for AEAD transformations. + * - For stream/CBC transformations and versions > SSL3, the + * MAC keys are not stored explicitly but maintained within + * md_ctx_{enc/dec}. + * - For stream/CBC transformations and version SSL3, the MAC + * keys are stored explicitly in mac_enc, mac_dec and have + * a fixed size of 20 bytes. These fields are unused for + * AEAD transformations or transformations >= TLS 1.0. + * - For transformations using an implicit IV maintained within + * the transformation context, its contents are stored within + * iv_{enc/dec}. + * - The value of ivlen indicates the length of the IV. + * This is redundant in case of stream/CBC transformations + * which always use 0 resp. the cipher's block length as the + * IV length, but is needed for AEAD ciphers and may be + * different from the underlying cipher's block length + * in this case. + * - The field fixed_ivlen is nonzero for AEAD transformations only + * and indicates the length of the static part of the IV which is + * constant throughout the communication, and which is stored in + * the first fixed_ivlen bytes of the iv_{enc/dec} arrays. + * Note: For CBC in SSL3 and TLS 1.0, the fields iv_{enc/dec} + * still store IV's for continued use across multiple transformations, + * so it is not true that fixed_ivlen == 0 means that iv_{enc/dec} are + * not being used! + * - minor_ver denotes the SSL/TLS version + * - For stream/CBC transformations, maclen denotes the length of the + * authentication tag, while taglen is unused and 0. + * - For AEAD transformations, taglen denotes the length of the + * authentication tag, while maclen is unused and 0. + * - For CBC transformations, encrypt_then_mac determines the + * order of encryption and authentication.
