GDPR Consent Record ID Regex for Go

What this pattern does

This page provides a well-structured, multi-part regular expression for matching gdpr consent record id, ported and verified for Go. Identity and credential patterns need both correctness and safety, since they're frequent targets for adversarial input. The snippet below is ready to drop into your Go project — whether you're validating in a Gin handler, a gRPC service, or a command-line tool.

Go Implementation

// GDPR Consent Record ID
// ReDoS-safe | RegexVault — Identity & PII > Consent & Compliance

package validation

import "regexp"

var gdprConsentRecordIdRe = regexp.MustCompile(`^[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$`)

func ValidateGdprConsentRecordId(s string) bool {
    return gdprConsentRecordIdRe.MatchString(s)
}

// Example
// fmt.Println(ValidateGdprConsentRecordId("550e8400-e29b-41d4-a716-446655440000")) // true

Test Cases

When to use this pattern

This pattern is drawn from the Identity & PII > Consent & Compliance category and carries a ReDoS-safe certification. That matters for Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Technical Notes

Consent records under GDPR Article 7 must be documented with: who consented, when, what they consented to, and how. UUID v4 is the standard format for consent record IDs. Link the consent ID to: user ID, timestamp, purpose, version of privacy notice, withdrawal date (if applicable).
