You can use the MacAlgorithmProvider to enumerate the available MAC algorithms and generate a symmetric key. You can use static methods on the CryptographicEngine class to perform the necessary encryption that creates the MAC value.Digital signatures are the public key equivalent of private key ...
共享的MAC密钥K或K1,共享的保密密钥K2 4. MAC有很多实现方式,比较通用的是基于hash算法的MAC,也就说HMAC是MAC的一个特例。 方法1:HMAC is a recipe forturning hash functions(such as MD5 or SHA256)into MACs.So HMAC-MD5 and HMAC-SHA256 are specific MAC algorithms, just like QuickSort is a specif...
OS X 10.11 价格 6 下载次数 401 官方网站 访问 Hash is your utility to validate the checksum of your file. With "Hash" you calculate the hash of a file and check the integrity of your file. Hash supports the following algorithms : Adler32 - CRC16 - CRC32 - DSS1 - GOST-MAC - MD4 ...
A larger hash bucket size will lower device forwarding performance. After you change the hash bucket size to a smaller value, you need to restart the switch. Verifying the Configuration Run the display mac-address hash-mode command to check the running and configured hash algorithms.翻訳...

MACTripleDES This algorithm uses TripleDES to encrypt the message, discarding all but the final 64 bits of the ciphertext. With keyed hashing algorithms, you can send the hash with the data, but you must keep the key secret. Note that this method does have limitations similar to the key ...
