Hands-On

The repository seekret-secrets is prepare to test seekret, and can be used to perform the following hands-on examples:

Inspect remote git repository:

seekret --rules $GOPATH/src/github.com/apuigsech/seekret/rules/ git https://github.com/apuigsech/seekret-secrets.git

Inspect local got repository:

git clone https://github.com/apuigsech/seekret-secrets.git /tmp/seekret-secrets
seekret --rules $GOPATH/src/github.com/apuigsech/seekret/rules/ git /tmp/seekret-secrets

Inspect only the last 2 commits:

seekret --rules $GOPATH/src/github.com/apuigsech/seekret/rules/ git -c 2 /tmp/seekret-secrets

Inspect with exceptions:

seekret --rules $GOPATH/src/github.com/apuigsech/seekret/rules/ -x /tmp/seekret-secrets/.exception_1 git /tmp/seekret-secrets

Library

Importing seekret Library

import seekret "github.com/apuigsech/seekret/lib"

Init Seekret context

s := seekret.NewSeekret()

Loading Rules

s.LoadRulesFromPath("/path/to/main/rues:/path/to/other/rules:/path/to/more/rules")

s.LoadRulesFromDir("/path/to/rules")

s.LoadRulesFromFile("/path/to/file.rule")

Loading Objects

opts := map[string]interface{} {
  "hidden": true,
  "recursive": false,
}
s.LoadObjects("dir", "/path/to/inspect", opts)

opts := map[string]interface{} {
  "count": 10,
}
s.LoadObjects("dir", "/repo/to/inspect", opts)

Loading Exceptions

s.LoadExceptionsFromFile("/path/to/exceptions/file")

Inspect

s.Inspect(5)

Get Inspect Results

secretsList := s.ListSecrets()

Rules

Secret identification is performed by using a set of rules specified on the rules files. Those files, with '.rule' extension are defined by using YAML following this format:

rulename:
  match: [regexp]
  unmatch:
    - [regexp]
    - [regexp]
    - ...

For the contents of a file is considered a secret, it must comply with the 'match' regexp and not comply ANY of the 'unmatch' reg rule and comply match ANY of the unmatch.

Exceptions

Exceptions determine conditions under which content should not be considered a secret. The exceptions are specified by using a YAML file that follows this format:

  ...
-
  rule: [rulename]
  object: [regexp]
  line: [linenumber]
  content: [regexp]
-
  ...

The conditions are optional, so it is not necessary to specify them all, but for a content deemed exception must meet all the specified conditions.

The meaning of the various conditions explained:

rule Contains the name of the rule.

object Contains a regexp that should match the object name (usually the filename).

line Contains the line number into the object.

content Contains a regexp that should match the content.
