 # ipfs-key
-A tool for easily generating ipfs keypairs. When run, it will write the bytes of
-the serialized private key to stdout. By default, a 2048 bit RSA key will be
-generated. The keysize can be changed by specifying the `-bitsize` option, and the
-key type can be changed by specifying the `-type` option (currently only RSA is
-implemented).

 ## Usage
+
+When run, it will write the bytes of
+the serialized private key to stdout. By default, a 2048 bit RSA key will be
+generated. In this case the key size can be changed by specifying the `-bitsize`
+option. The key type can be changed by specifying the `-type` option (rsa or
+ed25519).

 ```
-$ ipfs-key -bitsize=4096 > my.key
+$ ipfs-key -bitsize=4096 > my-rsa4096.key
+$ ipfs-key -type=ed25519 > my-ed.key
