Data Integrity

Data integrity ensures that data is not altered in transit.

Secure Shell connections use MACs (message authentication codes) to ensure data integrity. The client and server independently compute a hash for each packet of transferred data. If the message has changed in transit, the hash values are different and the packet is rejected. The MAC used for a given session is the MAC highest in the client's order of preference that is also supported by the server.

Reflection for Secure IT UNIX Client and Server supports the following MAC standards:

  • hmac-sha1

  • hmac-md5

  • hmac-sha1-96

  • hmac-md5-96

  • hmac-ripemd-160

  • hmac-sha256

  • hmac-sha2-256

  • hmac-sha512

  • hmac-sha2-512
