What are Certificate Policies?

Certificate Policies are defined sets of rules and procedures that govern the issuance and management of digital certificates. They specify the security requirements, validation procedures, and operational practices that a Certificate Authority (CA) must follow when issuing certificates.

  • Standardization: Ensures consistent certificate issuance across different CAs
  • Compliance: Helps meet regulatory and industry requirements
  • Trust: Establishes trust relationships between different PKI domains
  • Interoperability: Enables certificates to work across different systems

Certificate Policy Validator

Identity & Access
Paste the certificate in PEM format to validate its policies.
Enter the expected Certificate Policy OID to validate against.
Choose the level of policy validation to perform.
Common Policy Types
  • Domain Validated (DV): Basic domain ownership verification
  • Organization Validated (OV): Organization identity verification
  • Extended Validation (EV): Rigorous identity verification
  • Code Signing: Software code signing certificates
  • Client Authentication: User/client identity certificates
  • Email Protection: Email encryption and signing
Use Cases
  • PKI Compliance: Verify certificate policy compliance
  • Trust Validation: Ensure certificates meet trust requirements
  • Cross-Certification: Validate certificates across different PKIs
  • Audit Requirements: Meet regulatory audit requirements
  • Interoperability: Ensure certificates work across systems
  • Security Assessment: Evaluate certificate security posture
Example Policy OIDs

DigiCert EV: 2.16.840.1.114412.2.1

Let's Encrypt DV: 2.23.140.1.2.1

GlobalSign OV: 1.3.6.1.4.1.4146.1.20

Comodo EV: 1.3.6.1.4.1.6449.1.2.2.15

How Policy Validation Works
  1. Parse Certificate: Extract certificate policies extension
  2. Extract OIDs: Identify Certificate Policy OIDs
  3. Policy Mapping: Check for policy mappings
  4. Validation: Verify against expected policies
  5. Report: Generate validation results
Best Practices
  • Always validate certificate policies for critical systems
  • Use strict validation for high-security environments
  • Monitor policy changes and updates
  • Maintain a policy mapping database
  • Regularly audit certificate policy compliance
  • Document policy requirements and exceptions
