Developer: Chunghwa Telecom Laboratories (中華電信研究所)

Overview
The MOICA Certificate Extension Program is an official utility that enables eligible holders of Taiwan’s Citizen Digital Certificate (MOICA) to extend the validity of their certificate safely and conveniently. Designed and developed by Chunghwa Telecom Laboratories for the Ministry of the Interior, the program guides users through a secure, step-by-step process to update certificate validity on their existing smart card, helping ensure uninterrupted access to government e-services, digital signing, and encryption.

Key features

• Guided extension workflow: Clear, step-by-step instructions reduce errors and simplify the extension process.
• On-card update: Extends certificate validity on the existing MOICA smart card without replacing the card.
• Secure identity verification: Uses your card PIN and standards-compliant cryptographic procedures to protect personal data.
• Automatic checks: Verifies card status, certificate chain, and related metadata before applying changes.
• Compliance: Aligns with MOICA and Taiwan Government PKI policies and technical requirements.

Who should use it

• Individuals holding a valid MOICA Citizen Digital Certificate who need to extend its validity within the period allowed by MOICA policy.
• Users who rely on the MOICA certificate for government portals, online applications, digital signatures, or encrypted communications.

Prerequisites

• A valid MOICA Citizen Digital Certificate smart card.
• A compatible smart card reader.
• Your personal PIN and an active internet connection.
• A supported desktop environment as specified in the official MOICA/Chunghwa Telecom documentation.

Notes
