- **WebAuthn Support**: Comprehensive WebAuthn credential management and verification
- **Helper Functions**: Convenient wrapper functions that abstract complexity
- **Well-Tested**: Comprehensive test coverage with unit and integration tests
- **Production-Ready**: Battle-tested implementations with proper error handling

## Installation
```bash
go get github.com/sonr-io/common
```
## Quick Start
### IPFS Example
```go
package main
import (
"fmt"
"github.com/sonr-io/common"
)
func main() {
// Check if IPFS daemon is running
if !common.IsIPFSDaemonRunning() {
panic("IPFS daemon is not running")
}
// Store data
data := []byte("Hello, IPFS!")
cid, err := common.StoreData(data)
if err != nil {
panic(err)
}
fmt.Printf("Stored data with CID: %s\n", cid)
// Retrieve data
retrieved, err := common.RetrieveData(cid)
if err != nil {
panic(err)
}
fmt.Printf("Retrieved: %s\n", string(retrieved))
}
```
### WebAuthn Example
```go
package main
import (
"fmt"
"github.com/sonr-io/common"
)
func main() {
// Generate a challenge for WebAuthn ceremony
challenge, err := common.NewChallenge()
if err != nil {
panic(err)
}
fmt.Printf("Challenge: %s\n", challenge)
// Verify origin
origin := "https://example.com"
allowedOrigins := []string{"https://example.com", "https://app.example.com"}
if err := common.VerifyOrigin(origin, allowedOrigins); err != nil {
panic(err)
}
fmt.Println("Origin verified successfully!")
}
```
## IPFS Module
The IPFS module (`ipfs/`) provides a high-level interface for interacting with IPFS nodes.
### Core Functions
#### Client Management
```go
// Create a new IPFS client
client, err := common.NewIPFSClient()
// Or use the panic version for critical scenarios
client := common.MustGetIPFSClient()
// Check if daemon is running
if common.IsIPFSDaemonRunning() {
// Daemon is available
}
```
#### Data Storage
```go
// Store raw bytes
cid, err := common.StoreData([]byte("data"))
// Store a file with metadata
cid, err := common.StoreFile("document.txt", fileData)
// Store multiple files as a folder
files := map[string][]byte{
"file1.txt": []byte("content 1"),
"file2.txt": []byte("content 2"),
}
cid, err := common.StoreFolder(files)
```
#### Data Retrieval
```go
// Retrieve data by CID
data, err := common.RetrieveData("QmXxx...")
// Using client directly for advanced operations
client, _ := common.NewIPFSClient()
exists, err := client.Exists("QmXxx...")
entries, err := client.Ls("QmXxx...")
```
### Advanced IPFS Usage
```go
import "github.com/sonr-io/common/ipfs"
client, _ := ipfs.GetClient()
// Pin content
err := client.Pin("QmXxx...", "my-important-data")
// Unpin content
err := client.Unpin("QmXxx...")
// Check if pinned
pinned, err := client.IsPinned("ipns-name")
// Get node status
status, err := client.NodeStatus()
fmt.Printf("Peer ID: %s\n", status.PeerID)
fmt.Printf("Connected Peers: %d\n", status.ConnectedPeers)
```
## WebAuthn Module
The WebAuthn module (`webauthn/`) provides comprehensive support for WebAuthn authentication.
### Challenge Generation
```go
// Generate a cryptographic challenge (32 bytes, base64url encoded)
challenge, err := common.NewChallenge()
// Get the standard challenge length
length := common.ChallengeLength() // Returns 32
```
### Origin Verification
```go
// Verify origin against allowed list
allowedOrigins := []string{
"https://example.com",
"https://app.example.com:8080",
}
err := common.VerifyOrigin("https://example.com", allowedOrigins)
```
### Base64 URL Encoding
```go
// Encode data to URL-safe base64 (no padding)
encoded := common.EncodeBase64URL([]byte("data"))
// Decode URL-safe base64
decoded, err := common.DecodeBase64URL(encoded)
```
### Credential Management
#### Credential Creation (Registration)
```go
// Unmarshal credential creation response from client
credData := []byte(`{"id":"...","type":"public-key",...}`)
credResponse, err := common.UnmarshalCredentialCreation(credData)
// Parse and validate credential creation
parsedCred, err := common.ParseCredentialCreation(credData)
// Marshal credential for storage
jsonData, err := common.MarshalCredentialCreation(credResponse)
```
#### Credential Assertion (Authentication)
```go
// Unmarshal assertion response from client
assertionData := []byte(`{"id":"...","type":"public-key",...}`)
assertionResponse, err := common.UnmarshalCredentialAssertion(assertionData)
// Parse and validate assertion
parsedAssertion, err := common.ParseCredentialAssertion(assertionData)
// Marshal assertion for storage
jsonData, err := common.MarshalCredentialAssertion(assertionResponse)
```
### Advanced WebAuthn Usage
```go
import "github.com/sonr-io/common/webauthn"
// Create registration options
options := &webauthn.PublicKeyCredentialCreationOptions{
RelyingParty: webauthn.RelyingPartyEntity{
Name: "Example Corp",
ID: "example.com",
},
User: webauthn.UserEntity{
ID: []byte("user-id"),
Name: "user@example.com",
DisplayName: "User Name",
},
Challenge: challenge,
Parameters: []webauthn.CredentialParameter{
{Type: webauthn.PublicKeyCredentialType, Algorithm: -7}, // ES256
},
}
// Verify credential creation
clientDataHash, err := parsedCred.Verify(
storedChallenge,
verifyUser,
verifyUserPresence,
relyingPartyID,
rpOrigins,
rpTopOrigins,
rpTopOriginsVerify,
metadataProvider,
credParams,
)
// Verify credential assertion
err = parsedAssertion.Verify(
storedChallenge,
relyingPartyID,
rpOrigins,
rpTopOrigins,
rpTopOriginsVerify,
appID,
verifyUser,
verifyUserPresence,
credentialPublicKey,
)
```
