Use cases

• Services that want to mask their private IDs while keeping the ability to resolve them later

Installation

# will install `zorro-http` and `zorro-grpc` servers in your $GOPATH/bin
go get -u github.com/rodrigodiez/zorro/...

HTTP example

# Run zorro http server with memory storage
zorro-http --port 8080 --storage-driver memory --debug

# Run zorro http server with BoltDB storage (initialises a new db if $BOLTDB_PATH does not exist)
zorro-http --port 8080 --storage-driver boltdb -storage-path $BOLTDB_PATH --debug

# Run zorro http server with DynamoDB storage (requires tables to configured with an ID -string- hash key and AWS credentials available in the environment)
zorro-http --port 8080 --storage-driver dynamodb -dynamodb-keys-table $DINAMODB_KEYS_TABLE -dynamodb-values-table $DINAMODB_VALUES_TABLE -aws-region $AWS_REGION --debug

# Mask
curl -X POST http://localhost:8080/mask/<key>

# Unmask
curl -X POST http://localhost:8080/unmask/<value>

# Metrics
curl http://localhost:8080/debug/vars

gRPC example

# Same storage options as zorro-http are accepted, we omit them here for simplicity

# Run zorro gRPC server with memory storage
zorro-grpc --port 8080 --storage-driver memory

For interacting quickly with the gRPC server you can use a tool like grpcc.

Important: at the moment TLS is not supported so make sure to use your client in insecure mode.

Servers

• HTTP ✔️
• GRPC ✔️ (not tls support yet)
• HTTPS 🔜
• Twirp 🔜

Mask generators

• UUIDv4 ✔️

Storages

• In-Memory ✔️
• Bolt ✔️
• DynamoDB ✔️
• Google Cloud Datastore ✔️
• Redis 🔜
• MySQL 🔜

Protobuf

.proto files for the gRPC server can be found here

With these files you can automatically generate gRPC clients for multiple languages including Go, Java, C++, Python, Ruby, C#, PHP...

Have a look to the gRPC and Protocol Buffers documentation for more info.
