| - | Note that an RSA key is generated by finding two primes of half the length requested, and then multiplying them together. For example, if you ask PuTTYgen for a 1024-bit RSA key, it will create two 512-bit primes and multiply them. The result of this multiplication might be 1024 bits long, or it might be only 1023; so you may not get the exact length of key you asked for. This is perfectly normal, and you do not need to worry. The lengths should only ever differ by one, and there is no perceptible drop in security as a result. | ||

| - | DSA keys are not created by multiplying primes together, so they should always be exactly the length you asked for. | ||
