I want to use a random Blowfish key to encrypt files, so I did this: dd if=/dev/random of=mykey.bf count=100 bs=100 to create a 10K byte mykey.bf file. I can now encrypt foo.txt by doing: openssl enc -bf -pass file:mykey.bf -in foo.txt > foo.txt.encrypted However, "man enc" says "Blowfish and RC5 algorithms use a 128 bit key." Does this mean mykey.bf could've been just 16 bytes (128 bits) long? Or am I misunderstanding the word "key" here? -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
