Is there a way to search for a value in Hashicorp Vault? I am trying to write Golang code to search and list all locations a value appears in vault. It would be similar to golang's walk function on directories. Does anyone have a good approach for this? I was thinking of using concurrency to search vault for a value. Thank you
Below is a sample of the code I came up with. I am looking on how to make this faster by using concurrency. Is there a way to traverse a directory concurrently?
func walkDir(client *api.Client, path string) {
var value *api.Secret
var err error
if path != "" {
value, err = client.Logical().List(path)
} else {
path = vault_path
value, err = client.Logical().List(path)
}
if err != nil {
fmt.Println(err)
}
var datamap map[string]interface{}
datamap = value.Data
data := datamap["keys"].([]interface{})
for _, item := range data {
itemString := item.(string)
if strings.HasSuffix(itemString, "/") {
walkDir(client, path+itemString)
} else {
//its a secret
data := read(client, path+itemString)
if *searchKey!="" && searchForKey(data,*searchKey){
fmt.Println(path + itemString)
}
if *searchValue!="" && searchForValue(data,*searchValue){
fmt.Println(path + itemString)
}
}
}
}
func read(client *api.Client, path string) map[string]interface{} {
value, err := client.Logical().Read(path)
if err != nil {
fmt.Println(err)
}
values := value.Data
return values
}
func searchForValue(mapp map[string]interface{}, searchValue string) bool {
for _, value := range mapp {
if searchValue == value {
return true
}
}
return false
}
func searchForKey(mapp map[string]interface{}, searchKey string) bool {
for key := range mapp {
if searchKey == key {
return true
}
}
return false
}
You can
LIST
"directories" in Vault (I'm assuming you're just looking at thekv
engine). So treat it somewhat like a regular file-system: start at the root, list the entries, check the contents of each of them for that value, then iterate through each entry, listing its contents, and so forth.https://www.vaultproject.io/api-docs/secret/kv/kv-v1#list-secrets
