rsa - an old algorithm based upon the difficulty of factoring massive quantities. A important dimensions of at least 2048 bits is suggested for RSA; 4096 bits is healthier. RSA is getting previous and sizeable developments are now being produced in factoring.

As the thing is now the hostname can not be recognized as They can be hashed. A backup file is additionally produced at a similar site

By default ssh-keygen generates SSH important with 2048 bit measurement. You may as well specify the number of bits to be used for your keys by making use of -b
