I have a wireless router, and I want a difficult password that is still, in a way, easy to remember.
I came up with this idea to take the MD5, SHA-1, SHA-256, or whatever hash of a common English word, such as "superuser" and use the hash as the WPA2 key.
For example, let's say that "superuser" was my word of choice. If I chose SHA-1 has my hash, I would then set up my WPA2 key to be8e67bb26b358e2ed20fe552ed6fb832f397a507d
.
Is this a secure practice? Common English words are being used--in a way--in the key, but the key itself is actually a long, complex hexadecimal string.
