# Go Anonymizer
Simple anonymization tool for de-identifying your structurized data. You can easily anonymize your data with *Struct Tag* `anonymize:"{replacer}"`.
*Note: only string values are supported*
# Installation
$ go get github.com/hisdream86/go-anonymizer
# Example
```go
package main
import (
"crypto/sha256"
"encoding/hex"
"fmt"
anonymizer "github.com/hisdream86/go-anonymizer"
)
type Example struct {
// Anonymize with asterisk (*)
MaskedField string `anonymize:"asterisk"`
// Anonymize to empty string ("")
EmptyField string `anonymize:"empty"`
// Anonymize with custom handler
CustomField string `anonymize:"mysha256"`
// Anoymize nested Field
NestedField struct {
MaskedField string `anonymize:"asterisk"`
}
// Anonymize array Field
ArrayField []string `anonymize:"asterisk"`
// Don't anonymize
PlainField string
}
type NestedField struct {
MaskedField string `anonymize:"asterisk"`
}
func main() {
var target = Example{
MaskedField: "MaskedField",
EmptyField: "EmptystringField",
CustomField: "CustomField",
PlainField: "PlainField",
NestedField: NestedField{
MaskedField: "NestedMaskedField",
},
ArrayField: []string{"Field 1", "Field 2"},
}
// Register custom replacer for anonymizing data with SHA256 hashing
anonymizer.AddCustomReplacer("mysha256", func(source string) string {
h := sha256.New()
h.Write([]byte(source))
return hex.EncodeToString(h.Sum(nil))
})
if err := anonymizer.Anonymize(&target); err != nil {
fmt.Println("Fail to anonymize target data.")
}
fmt.Println(target)
}
```
# Replacers
## Default Replacers
Go Anonymizer provides following default replacers.
### asterisk
Replace your data with multiple asterisks `*`. The number of asterisk character is same with your string's length.
> "Hello World" -> "***********"
### empty
Replace your data with empty string.
> "Hello World" -> ""
## Custom Replacers
If you want to use your custom replacer, you can use `AddCustomReplacer()` and `RemoveCustomReplacer()`.
