Additional Considerations
Signature Creation
Signed content is entire Document structure except signature section for I signature type and entire structure + previous I signature for S type of signature. SHA256 hashing used for creating hash of the elements to sign.
More details on how to define structure of the document to hash, create canonical version, apply hashing, sign the hash and then embed the signature are provided in section Signature Creation.
Signature Validation
The validation rules for signatures are:
- Base64 encoded value that is a valid CADES-BES structure.
- CADES-BES signing certificate is valid at the date of submission of document for validation.
- Signing certificate is issued to:
- issuer of the document, i.e., taxpayer registration number matches in certificate and document,
- person representative who is active representative of taxpayer at the document issuance date and time.
- CADES-BES signature is valid RSA signature created using one of the approved eSeal or natural person signature certificates in Egypt.
