Make an destination key with a certain key type

    ./keygen privkey.dat <number>

or

    ./keygen privkey.dat <key name>

### keyinfo

Prints information about an I2P private key

#### Usage

Print just the b32 address for this key

     ./keyinfo privatekey.dat

... just the base64 address

    ./keyinfo -d privatekey.dat

Print all info about the public key

    ./keyinfo -v privatekey.dat

### regaddr

Generate authentication string to register a domain on reg.i2p and stats.i2p

    ./regaddr domain.dat domain.i2p > auth_string.txt
    cat auth_string.txt

Send output of auth_string to http://reg.i2p/add and http://stats.i2p/i2p/addkey.html

To register a subdomain, use [`regaddr_3ld`](#regaddr_3ld)

### regaddr_3ld

Generate authentication string to register a subdomain on reg.i2p and stats.i2p in 3 steps

    ./regaddr_3ld step1 sub_domain.dat sub.domain.i2p > step1.txt
    ./regaddr_3ld step2 step1.txt domain.dat domain.i2p > step2.txt
    ./regaddr_3ld step3 step2.txt sub_domain.dat > step3.txt
    cat step3.txt

Send output of auth_string to http://reg.i2p/add and http://stats.i2p/i2p/addkey.html

### regaddralias

Generate authentication string to register an alias address for existing domain on reg.i2p and stats.i2p

    ./regaddralias domain-oldkeys.dat domain-newkeys.i2p domain > auth_string.txt
    cat auth_string.txt

Send output of auth_string to http://reg.i2p/add and http://stats.i2p/i2p/addkey.html

### x25519

Generate key pair with output in base64 encoding. Now the x25519 keys are used for authentication with an encrypted LeaseSet.
