[ale] SSH KEy sizes

[Christopher Fowler]

 From key-gen(1)

     -b bits
             Specifies the number of bits in the key to create.  Minimum is
             512 bits.  Generally 1024 bits is considered sufficient, and key
             sizes above that no longer improve security but make things
             slower.  The default is 1024 bits.


I've dealt with some companies in the past that have
claimed that bigger keys = better security.  Based on the
man page entry that is not so.  Does a key size of 2048 really matter
vs one of 1024?

Thanks,
Chris
