随后需要回答一系列问题，以帮助产生一对密钥。首先遇到的问题是要求选择密钥使用的算法：
Please select what kind of key you want:(1) DSA and ElGamal (default)(2) DSA (sign only)(5) RSA (sign only)Your selection? 1 |
其中，DSA是数字签名算法，RSA和ElGamal是两种不同原理的非对称密钥算法。通常可以选择“1”，这样生成的密钥可以同时用作签名和加密两种用途。
接着，会要求选择密钥的长度：
DSA keypair will have 1024 bits.About to generate a new ELG-E keypair.minimum keysize is 768 bitsdefault keysize is 1024 bitshighest suggested keysize is 2048 bitsWhat keysize do you want? (1024) 2048Requested keysize is 2048 bits |
