Mastering Binary Re-signingfor App Security
Learn the importance of binary re-signing to ensure your app's security, integrity, and seamless updates without needing a complete rebuild.
Why Re-signing is Important
- Re-signing a binary is essential for updating the signature used to verify an app's authenticity.
- It ensures that the app has not been tampered with and comes from a trusted source.
- Common reasons to re-sign a binary include transferring app ownership to a new developer account, renewing a certificate that has expired or been revoked, or changing the app's name or bundle identifier.
