+# i2pd-tools
+
+This repository contains tools that supplement i2pd.
+
+Notice: git submodules are used so make sure to clone this repository recursively
+
+    git clone --recursive https://github.com/purplei2pd/i2pd-tools
+
+## Tools included
+
+### keygen
+
+Generate an i2p private key
+
+#### Usage
+
+Make a DSA-SHA1 destination key
+
+    ./keygen privkey.dat
+
+Make an destination key with a certain key type
+
+    ./keygen privkey.dat <number>
+
+or
+
+    ./keygen privkey.dat <key name>
+
+
+| key name             | number |
+| -------------------- | ------ |
+| DSA-SHA1             | 0      |
+| ECDSA-SHA256-P256    | 1      |
+| ECDSA-SHA384-P384    | 2      |
+| ECDSA-SHA512-P521    | 3      |
+| RSA-SHA256-2048      | 4      |
+| RSA-SHA384-3072      | 5      |
+| RSA-SHA512-4096      | 6      |
+| EDDSA-SHA512-ED25519 | 7      |
+
+
+
+### 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
