Making Sense of Hashed Hosts in ~/.ssh/known_hosts

I don’t expect you to follow this post completely, but it’s so amazingly cool, I have to blog it. Consider the hashed sections of ~/.ssh/known_hosts file for (recent) OpenSSH clients, not including the public key parts: |1|kFJT5z0x3ndyutgZ4E5pRk+ORBA=|hzXvdYUudo+qK9BGlFWtSAUXlXc= |1|8wo1+FO0hkATPgQZoeNHeIlvAjw=|dt/a9jz9CnLKP72j+Jr8MKMjgEE= |1|pvBQEKEGLnH0RCJr+8Dmqqnvlrs=|fJJvjyG/TmHFnuIX57nDThq/C4M= |1|HKV4DzgDkajXoUHf9B82JBu7J10=|c/K+MdJvWaZeJFs/W7iqhqo0wvE= |1|rtvQhRVnNanQZYkLUMbjoBGNhn0=|0U6a1LUQqLL6P1T2Wji3VWw69pw= |1|0ziSYi4c+xBXGEBZcNN1LMhYUc4=|qRSN5GSPyQi+fmaVz2zNwkmKoy8= |1|6nv6Vpk3AYgICHxJGVgVdsYRuq0=|fBNOIz1l3RW+N61jyDPunKX9n7E= |1|+b4uA+Mq7RHRAFW21qv8aO3rIRs=|1eizMri01IxEKrXquBnwTYP61Ow= |1|BkB0PZu2qtsLID/Ibe/D68gANQU=|qW6uAzcpecOOKNI4zEvngyfpGkI= |1|n+QrRn7QXeAJ5hRe2M8v8IspihE=|EqUxXdSeIF1cl1fQjl5zILebkGY= |1|BOKuKnWojy028tJf9Y671lws0d0=|SuBQJmJZp5JNVYG/rP9yb9ZhJcE= |1|WACsxtodOiM89kf4rNPLgF1CXZ4=|UTccVeLDZJF3wlH8V05XJNlsOBw= |1|o6FFoirXYblM7wBMdeJDYGMPI58=|5jJB7T7itY702ZHHByXtSpGk9SE= The column fields are similar to [...]

Boycott GoDaddy

If there are thousands of files (as is often the case at my job), this command is [...]

Steganography

I have been familiar with steganography for a number of years. In fact, back when I was in middle school, I developed a fascination for encryption, and hiding messages, mostly so I could pass notes back and forth to classmates during class. It wasn’t long before I found “invisible ink”, which is a form of [...]
