Pointer to output data * for SM2 private decrypt. In this case the underlying array should have been allocated with enough memory to hold plaintext output (at least en- crypted text length). The message.length field will be overwritten by the PMD with the decrypted length. Definition at line 693 of file rte_crypto_asym.h. rte_crypto_param cipher Pointer to input data * to be decrypted for SM2 private decrypt. Pointer to output data * for SM2 public encrypt. In this case the underlying array should have been allocated with enough memory to hold ciphertext output (at least X bytes for prime field curve of N bytes and for message M bytes, where X = (C1 || C2 || C3) and computed based on SM2 RFC as C1 (1 + N + N), C2 = M, C3 = N. The cipher.length field will be overwritten by the PMD with the encrypted length. Definition at line 709 of file rte_crypto_asym.h. struct rte_crypto_ec_point c1 This field is used only when PMD does not support the full process of the SM2 encryption/decryption, but the elliptic curve part only. In the case of encryption, it is an output - point C1 = (x1,y1). In the case of decryption, if is an input - point C1 = (x1,y1). Must be used along with the RTE_CRYPTO_SM2_PARTIAL flag. Definition at line 724 of file rte_crypto_asym.h. struct rte_crypto_ec_point kp This field is used only when PMD does not support the full process of the SM2 encryption/decryption, but the elliptic curve part only. It is an output in the encryption case, it is a point [k]P = (x2,y2). Must be used along with the RTE_CRYPTO_SM2_PARTIAL flag. Definition at line 735 of file rte_crypto_asym.h. rte_crypto_uint id The SM2 id used by signer and verifier. Definition at line 749 of file rte_crypto_asym.h. rte_crypto_uint k The SM2 per-message secret number, which is an integer in the interval (1, n-1). If the random number is generated by the PMD, the 'rte_crypto_param.data' parameter should be set to NULL.
