MEGA Company · Document Authentication
Verify a signed or sealed document
Enter the verification code printed on the document's Execution page, or upload the PDF you received. MEGA checks the signatures, whether the file changed after signing, the certificates, and whether each signer held the authority to sign.
Kiswahili: Hakiki uhalali wa hati iliyosainiwa au kugongwa muhuri na MEGA kwa kuweka namba ya uthibitisho au kupakia PDF.
- Valid: intact, signed with trusted certificates and a trusted time, and every signer held the required authority.
- Invalid / modified: a signature fails or the file was changed after signing. Do not rely on it.
- Untrusted / indeterminate: the file is intact, but certificate trust or time evidence is not established (for example during MEGA's sandbox pilot).
- Authorisation failed: the signatures may be intact, but MEGA's records do not show the authority to sign it.
