WebMar 3, 2024 · It is easy to generate a cryptographic hash from a given input, but impossible to generate the input from the hash. This means that if a client holds the correct input, they can generate the cryptographic hash and compare its value to verify whether they possess the correct input. SSH uses hashes to verify the authenticity of messages.
