WebbReturn Values. An array of available cipher methods. Note that prior to OpenSSL 1.1.1, the cipher methods have been returned in upper case and lower case spelling; as of OpenSSL 1.1.1 only the lower case variants are returned. WebbThe SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and CTR modes respectively. RETURN VALUES ¶ These functions return a EVP_CIPHER structure that contains the implementation of the symmetric cipher. WebbSM4-CFB SM4-CFB relies on feedback provided by successive ciphertext segments to generate output blocks. The plaintext given must be a multiple of the block size. Similar to SM4-CBC, SM4-CFB requires an IV that is unpredictable for a particular execution of the encryption process. computer keyboard online keays
