不过由于椭圆曲线算法的优点,使其取代 RSA/DSA 而成为新一代通用的非对称加密算法成为可能,至少SET协议的制定者们已经把它作为下一代SET协议中缺省的公钥密码算法了。 参考: 1)http://security.stackexchange.com/questions/5096/rsa-vs-dsa-for-ssh-authentication-keys 2)http://iask.sina.com.cn/b/7132379.h...
从商业角度来看,RSA显然是赢家,商业RSA证书比DSA证书被更广泛地部署。 关键是:(当查看)说DSA密钥必须长1024位,才能符合NIST(美国国家标准技术研究院)的FIPS 186-2(数字签名标准).因此,虽然理论上可能有更长的DSA密钥(FIPS 186-2也明确允许它们),但你仍然受限于1024位。 今天,你最好使用RSA 2048位密钥(也可以...

same security as RSA at a shorter key length, i.e. 1280-bit DSA has about the same security as 1536-bit RSA. For that reason I always use 1280-bit DSA key pairs for SSH authentication, i.e. the keys are generated with "ssh-keygen -t dsa -b 1280", both for the server host key...

You can use “dsa” instead of the “rsa” after the-tto generate a DSA key. The number after the-bspecifies the key length in bits. After executing the command it may take some time to generate the keys (as the program waits for enough entropy to be gathered to generate random number...

Many years the default for SSH keys was DSA or RSA. There is a new kid on the block, with the fancy name Ed25519. Let's have a look at this new key type.
$sshng$1$ stands for RSA, DSA keys using AES-128 $sshng$2$ stands for bcrypt PBKDF + AES-256-CBC / AES-256-CTR $sshng$3$ stands for EC keys using AES-128 $sshng$4$ stands for RSA, DSA keys using AES-192 $sshng$5$ stands for RSA, DSA keys using AES-256 Disclaimer It'...
If a server supports both an RSA and an ML-DSA cert then in most cases the RSA cert will always be selected by default. E.g. using the certs/keys in test/certs and starting s_server like this: $ openssl s_server -cert server-ml-dsa-44-cert.pem -key server-ml-dsa-44-key.pem ...
