Cryptography is a field of study that focuses on concepts like encryption and decryption which are utilized for secure communication, whereas encryption is encoding a message through an algorithm. Cryptography involves many different methods and techniques on one hand, but on the other hand, ...
(Offset 8, Length 9)的数据就是 AlgorithmIdentifier,它的值应该是 rsaEncryption,即1.2.840.113549.1.1.1,对应到 DER 上就是2A 86 48 86 F7 0D 01 01 01。 (Offset 32, Length 257)的数据就是 modulus 的 n。 (Offset 291, Length 3)的数据就是 publicExponent 的 e,值就是 65537 (0x010001)。
If the sender created the // original message buffer from a string, the sender must tell the recipient what // BinaryStringEncoding value was used. Here, BinaryStringEncoding.Utf8 is used to // convert the message to a buffer before encryption and to convert the decrypted // ...
代表RSA Optimal Asymmetric Encryption Padding (OAEP) 加密演算法的命名空間統一資源識別元 (URI)。 這個欄位為常數。 XmlEncSHA256Url 代表SHA-256 演算法的命名空間統一資源識別元 (URI)。 這個欄位為常數。 XmlEncSHA512Url 代表SHA-512 演算法的命名空間統一資源識別元 (URI)。 這個欄位為常數。 Xm...
Roman encryption and cyphers Circa 60 BC:Julius Caesar invents a cypher that shifts characters by three places in the alphabet:A becomes D, B becomes E, etc. A simple and effective encoding method at that time. Surprisingly, in the 2000s, Bernardo Provenzano, the Sicilian Mafia boss, still...
