BloxID

This package, bloxid, implements typed guids for identifying resource objects globally in the system. Resources are not specific to services/applications but must contain an entity type.

Typed guids have the advantage of being globally unique, easily readable, and strongly typed for authorization and logging. The trailing characters provide sufficient entropy to make each resource universally unique.

bloxid package provides methods for generating and parsing versioned typed guids.

bloxid supports different schemes for the unique entity id portion of the bloxid

• extrinsic
• hashid
• random

bloxids are Fully Qualified Names (FQN), dot separated, and composed of the following parts:

  <version>
  |     <entity_domain>
  |     |   <entity_type>
  |     |   |     <entity_realm>
  |     |   |     |        <entity_id>
  |     |   |     |        |
  blox0.iam.group.us-com-1.tshwyq3mfkgqqcfa76a5hbr2uaayzw3h

At Infoblox, the entity_id is unique within that realm, domain, and type combination.

Scheme - extrinsic

create bloxid from extrinsic id

v0, err := NewV0("",
            WithEntityDomain("iam"),
            WithEntityType("user"),
            WithRealm("us-com-1"),
            WithSchemer(WithExtrinsic("123456")),
        )
// v0.String(): "blox0.iam.user.us-com-1.ivmfiurrgiztinjweaqcaiba"
// v0.Decoded(): "123456"

parse bloxid to retrieve extrinsic id

parsed, err := NewV0("blox0.iam.user.us-com-1.ivmfiurrgiztinjweaqcaiba")
// parsed.Decoded(): "123456"

Scheme - hashid

create bloxid from hashid

v0, err := NewV0("",
            WithEntityDomain("infra"),
            WithEntityType("host"),
            WithRealm("us-com-1"),
            WithSchemer(WithHashIDInt64(1)),
            WithHashIDSalt("test"),
        )
// v0.String(): "blox0.infra.host.us-com-1.jbeuiwrsmq3tkmzwmuzwcojsmrqwemrtgy3tqzbvhbsdizjvhe2dkn3cgzrdizlb"
// v0.HashIDInt64(): 1

parse bloxid to retrieve hashid

parsed, err := NewV0("blox0.infra.host.us-com-1.jbeuiwrsmq3tkmzwmuzwcojsmrqwemrtgy3tqzbvhbsdizjvhe2dkn3cgzrdizlb",
    WithHashIDSalt("test")
)
// parsed.HashIDInt64(): 1

Scheme - random

create bloxid from generated random id

v0, err := NewV0("",
            WithEntityDomain("iam"),
            WithEntityType("group"),
            WithRealm("us-com-1"),
        )
// v0.String(): "blox0.iam.group.us-com-1.tshwyq3mfkgqqcfa76a5hbr2uaayzw3h"
// v0.Encoded(): "tshwyq3mfkgqqcfa76a5hbr2uaayzw3h"
// v0.Decoded(): "9c8f6c436c2a8d0808a0ff81d3863aa0018cdb67"

parse bloxid to retrieve the unique entity id portion of the bloxid

parsed, err := NewV0("blox0.iam.group.us-com-1.tshwyq3mfkgqqcfa76a5hbr2uaayzw3h")
// parsed.Encoded(): "tshwyq3mfkgqqcfa76a5hbr2uaayzw3h"
// parsed.Decoded(): "9c8f6c436c2a8d0808a0ff81d3863aa0018cdb67"

create bloxid from unique entity id portion of a previously generated bloxid with random scheme

v0, err := NewV0("",
            WithEntityDomain("iam"),
            WithEntityType("group"),
            WithRealm("us-com-1"),
            WithSchemer(WithRandomEncodedID("tshwyq3mfkgqqcfa76a5hbr2uaayzw3h")),
        )
// v0.String(): "blox0.iam.group.us-com-1.tshwyq3mfkgqqcfa76a5hbr2uaayzw3h"
// v0.Encoded(): "tshwyq3mfkgqqcfa76a5hbr2uaayzw3h"
// v0.Decoded(): "9c8f6c436c2a8d0808a0ff81d3863aa0018cdb67"
