Cipher strength is a measure of how strongly data is
secured when it is sent over the internet. The number of
bits used in the numerical code determines the cipher
strength. The greater the number of bits that make up the
code, the greater the cipher strength. For example,
Canada's internal revenue service specifies that before you
send tax information to its offices, the cipher strength of
your transmitted data must be at least 128-bit. In
comparison, the cipher strength of Internet Explorer 8 is
256-bit.

Now to the second part of your question, how cipher
strength applies to certificates: As cipher strength
applies to the level of encryption of your transmitted
data, certification refers to identifying that the website
to which you are sending your encrypted data is, in fact,
the site that you think it is. Certification is another
way of saying positive identification; it is verifying a
site through its digital fingerprints.
