+Key API
+=======
+
+#### `gen`
+
+> Generate a new key
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.key.gen(name, options, [callback])
+
+Where:
+
+- `name` is a local name for the key
+- `options` is an object that contains following properties
+  - 'type' - the key type, one of 'rsa'
+  - 'size' - the key size in bits
+
+`callback` must follow `function (err, key) {}` signature, where `err` is an Error if the operation was not successful. `key` is an object that describes the key; `name` and `id`.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.add(
+  'my-key', 
+  { type: 'rsa', size: 2048 }, 
+  (err, key) => console.log(key))
+
+
+{ 
+  Name: 'my-key',
+  Id: 'Qmd4xC46Um6s24MradViGLFtMitvrR4SVexKUgPgFjMNzg'
+}
+```
+
+#### `list`
+
+> List all the keys
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.key.list([callback])
+
+`callback` must follow `function (err, keys) {}` signature, where `err` is an Error if the operation was not successful. `keys` is an object with the property `Keys` that is an array of `KeyInfo` (`name` and `id`)
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.list((err, keys) => console.log(keys))
+
+{ 
+  Keys: [
+    { Name: 'self',
+      Id: 'QmRT6i9wXVSmxKi3MxVRduZqF3Wvv8DuV5utMXPN3BxPML' },
+    { Name: 'my-key',
+      Id: 'Qmd4xC46Um6s24MradViGLFtMitvrR4SVexKUgPgFjMNzg' } 
+  ]
+}
+```
+
+#### `rm`
+
+> Remove a key
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.key.rm(name, [callback])
+
+Where:
+- `name` is the local name for the key
+
+`callback` must follow `function (err, key) {}` signature, where `err` is an Error if the operation was not successful. `key` is an object that describes the removed key.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.rm('my-key', (err, key) => console.log(key))
+
+{ 
+  Keys: [
+    { Name: 'my-key',
+      Id: 'Qmd4xC46Um6s24MradViGLFtMitvrR4SVexKUgPgFjMNzg' } 
+  ]
+}
+```
+
+#### `rename`
+
+> Rename a key
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.key.rename(oldName, newName, [callback])
+
+Where:
+- `oldName` is the local name for the key
+- `newName` a new name for key
+
+`callback` must follow `function (err, key) {}` signature, where `err` is an Error if the operation was not successful. `key` is an object that describes the renamed key.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.rename(
+  'my-key', 
+  'my-new-key',
+  (err, key) => console.log(key))
+
+{ 
+  Was: 'my-key',
+  Now: 'my-new-key',
+  Id: 'Qmd4xC46Um6s24MradViGLFtMitvrR4SVexKUgPgFjMNzg',
+  Overwrite: false
+}
+```
