◆Signature algorithm (签名所使用的算法) 就是指的这个数字证书的数字签名所使用的加密算法,这样就可以使用证书发布机构的证书里面的公钥,根据这个算法对指纹进行解密。指纹的加密结果就是数字签名(第1.5节中解释过数字签名)。 ◆Thumbprint, Thumbprint algorithm (指纹以及指纹算法) 这个是用来保证证书的完整性的,也...

So how does the PGP encryption algorithm work?Here’s an example of PGP in action:Let’s say Sara wants to send Jane a private email and she doesn’t want their boss Bill to see it; Jane now needs to generate two keys. One public and one private; She now shares the public key ...
Finally, the third use PGP has is file encryption. Since PGP uses the RSA algorithm it offers a very secure option to encrypt files, in particular when used together with a good cyber threat detection solution.Pros and Cons of PGPLike everything else in life, PGP is not perfect either. ...
Inc. themselves changed the default key format from DH/DSS to RSA. They also changed the default key size from 1024-bits to 2048-bits. This change was primarily motivated by the fact that the Digital Signature Standard is dependent on the SHA-1 hash algorithm, which has proven increasibly...
这句话是错的, ed25519是 EdDSA 算法的一种,只是一种签名算法, EdDSA 全称Edwards-curve Digital Signature Algorithm,爱德华椭圆曲线实现的数字签名算法。 上面的话多出现在替换SSH默认的RSA算法为ed25519的文章中出现。其实SSH协议中的非对称算法 并不是用来加解密信息的,而只是用来认证,正确的说法是ed25519签名和...
