vault

README

Usage

Run the vaultd service:

cd vault/cmd/vaultd
go run main.go

Hash a password:

curl -XPOST -d'{"password":"MySecretPassword123"}' localhost:8080/hash

{"hash":"$2a$10$L/Riz9xbgTBDn7F6uLInq.9Tr67PvBCmxzrLgemitnRM53ht7LGpC"}

Validate passwords with hashes:

curl -XPOST -d'{"password":"MySecretPassword123","hash":"$2a$10$L/Riz9xbgTBDn7F6uLInq.9Tr67PvBCmxzrLgemitnRM53ht7LGpC"}' localhost:8080/validate

{"valid":true}

or if you get the password wrong:

curl -XPOST -d'{"password":"NOPE","hash":"$2a$10$L/Riz9xbgTBDn7F6uLInq.9Tr67PvBCmxzrLgemitnRM53ht7LGpC"}' localhost:8080/validate

{"valid":false}

Compiling protobuf

Install proto3 from source:

brew install autoconf automake libtool
git clone https://github.com/google/protobuf
./autogen.sh ; ./configure ; make ; make install

Update protoc Go bindings:

go get -u github.com/golang/protobuf/{proto,protoc-gen-go}

See also https://github.com/grpc/grpc-go/tree/master/examples

Compile the protobuf (from inside pb folder):

protoc vault.proto --go_out=plugins=grpc:.

Types

type Endpoints

type Endpoints struct {
	HashEndpoint     endpoint.Endpoint
	ValidateEndpoint endpoint.Endpoint
}

Endpoints represents all endpoints for the vault Service.

func (Endpoints) Hash

func (e Endpoints) Hash(ctx context.Context, password string) (string, error)

Hash uses the HashEndpoint to hash a password.

func (Endpoints) Validate

func (e Endpoints) Validate(ctx context.Context, password,
	hash string) (bool, error)

Validate uses the ValidateEndpoint to validate a password and hash pair.

type Service

type Service interface {
	Hash(ctx context.Context, password string) (string, error)
	Validate(ctx context.Context, password, hash string) (bool, error)
}

Service provides password hashing capabilities.

func NewService

func NewService() Service

NewService makes a new Service.
