-pkcs 选项指定加密处理过程中数据的填充方式,对于填充,可选项有:-pkcs, -oaep, -ssl, -raw,默认是-pkcs,即按照PKCS#1 v1.5规范进行填充 1.4 私钥解密 使用私钥Key.pem对加密后的数据msg.bin.enc进行解密,并将结果存放到msg.bin.dec文件中: $ openssl rsautl -in msg.bin.enc -out msg.bin.dec -inkey...
导出密钥:将公钥和私钥导出为字节格式。 加密消息:使用公钥和PKCS1_v1_5算法加密消息。 解密过程 紧接着,我们将使用私钥对前面加密的消息进行解密。 fromCrypto.CipherimportPKCS1_v1_5# 使用私钥解密消息cipher=PKCS1_v1_5.new(RSA.import_key(private_key))decrypted_msg=cipher.decrypt(ciphertext,None)print...
