# SSH Agent Module
|
||||
|
||||
SSH agent management library for V language. Provides secure key handling, agent lifecycle control, and remote integration.
|
||||
|
||||
## Features
|
||||
|
||||
* Manage SSH keys (generate, load, import)
|
||||
* Single agent per user with auto-cleanup
|
||||
* Start/stop/reset agent easily
|
||||
* Diagnostics and status checks
|
||||
* Push keys to remote nodes & verify access
|
||||
* Security-first (file permissions, socket handling)
|
||||
|
||||
## Platform Support
|
||||
|
||||
* Linux, macOS
|
||||
* Windows (not yet supported)
|
||||
|
||||
## Quick Start
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.osal.sshagent
|
||||
|
||||
mut agent := sshagent.new()!
|
||||
|
||||

||||
|
||||
mut key := agent.generate('my_key', '')!
|
||||
key.load()!
|
||||
println(agent)
|
||||
```
|
||||
|
||||
### hero
|
||||
## Usage
|
||||
|
||||
there is also a hero command
|
||||
|
||||
```js
|
||||
//will add the key and load (at this stage no support for passphrases)
|
||||
!!sshagent.key_add name:'myname'

privkey:'

|

'
|
||||
### Agent
|
||||
|
||||
```v
|
||||
mut agent := sshagent.new()!
|
||||
mut agent := sshagent.new(homepath: '/custom/ssh/path')!
|
||||
mut agent := sshagent.new_single()!
|
||||
```
|
||||
|
||||
### Keys
|
||||
|
||||
```v
|
||||
mut key := agent.generate('my_key', '')!
|
||||
agent.add('imported_key', privkey)!
|
||||
key.load()!
|
||||
if agent.exists(name: 'my_key') { println('Key exists') }
|
||||
agent.forget('my_key')!
|
||||
```
|
||||
|
||||
### Agent Ops
|
||||
|
||||
```v
|
||||
println(agent.diagnostics())
|
||||
println(agent.keys_loaded()!)
|
||||
agent.reset()!
|
||||
```
|
||||
|
||||
### Remote
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.builder
|
||||
|
||||
mut node := builder.node_new(ipaddr: 'user@remote:22')!
|
||||
agent.push_key_to_node(mut node, 'my_key')!
|
||||
```
|
||||
|
||||
## Security
|
||||
|
||||
* Private keys set to `0600`
|
||||
* Secure sockets & user isolation
|
||||
* Validated inputs & safe memory handling
|
||||
|
||||
## Examples
|
||||
|
||||
See `examples/osal/sshagent/` for demos.
|
||||
|
||||
