PuTTY Key Generator, also known by the PuTTYgen moniker, is a small yet efficient program that can generate RSA and DSA keys for use with the OpenSSH authorized_keys file.It is a component of A lot of implementations do not allow encryption with a private key. Trying to simulate signature generation using private keys is often not possible. Implementations of public key operations often assume a small public exponent. Furthermore, they will generally not apply the Chinese Remainder Theorem that is used to speed up private key To create the public and a private keys, on the computer from which you will be connecting to various computers, generate SSH key pairs as follows (I recommend using the RSA algorithm): [user_name@local_host ~]$ ssh-keygen -t rsa -b 2048. Generating public/private rsa key pair. Note: The -t option specifies the type of the key to create. Most Public Key Infrastructures (PKIs) mandate local key generation; however, there are some PKIs that also support centralized key generation (e.g., the public-private key pair is generated by a Certification Authority). Save a public key file from PuTTYgen, and copy that into the .ssh2 subdirectory of your account home directory. In the same subdirectory, edit (or create) a file called authorization. In this file you should put a line like Key mykey.pub, with mykey.pub replaced by the name of your key file. Other SSH Servers
Once the progress bar becomes full, the actual key generation computation takes place. This may take from several seconds to several minutes. When complete, the public key should appear in the Window. You can now specify a passphrase for the key. You should save at least the private key by clicking Save private key.

Private-key and password Advanced generator is the updated version and now available to users. This version has advanced capabilities and a more reliable algorithm. whit the advanced generator only one private key is given from the blockchain database hack. You get the exact private-key of any address you need
PuTTY Key Generator is a dedicated key generator software for Windows. You can generate RSA key pair as well as DSA, ECDSA, ED25519, or SSH-1 keys using it. In order to create a pair of private and public keys, select key type as RSA (SSH1/SSH2), specify key size, and click on Generate button. While the key generation process goes on, you can move mouse over blank area to generate randomness.
