Where can I find the Public Certificate for Digital Signature validation? Open or Close

Public certificate for Digital signature validation can be downloaded from here.

How this Aadhaar Offline Paperless eKYC document is different from the other identification documents produced offline by individuals? Open or Close

Identity verification can simply be accomplished by providing an identity document like PAN card, Passport etc to the service provider. However, all these documents, which may be used for identification can still be forged and faked which may or may not be possible to verify offline instantaneously. The document verifier has no technological means to verify the authenticity of the document or the information it contains and has to trust the document producer. Whereas, the XML file generated by the Aadhaar number holder using Aadhaar Paperless Offline e-KYC is digitally signed document using UIDAI digital signature. Thus, the service provider can verify the demographic contents of the file and certify it to be authentic when doing the offline verification

Can this Offline Paperless eKYC document be shared to other entities by the Service Provider? Open or Close

Service Providers shall not share, publish or display either XML or Share Code or its contents with anyone else. Any non-compliance of these actions shall invite actions under Sections 29(2), 29 (3), 29(4) and 37 of The Aadhaar Act, 2016 (as amended) and sub regulation 1A of regulation 25, regulation 14A of The Aadhaar (Authentication and Offline Verification) Regulation, 2021 and regulation 6 and 7 of The Aadhaar (Sharing of Information) Regulation, 2016.

How will service providers use Aadhaar Offline e-KYC? Open or Close

The process of Aadhaar Offline e-KYC Verification by Service Provider is:

Once service provider obtains the ZIP file, it extracts the XML file using the password (share code) provided by the Aadhaar number holder.
The XML file will contain the demographic details such as Name, DOB, Gender and Address. Photo is in base 64 encoded format which can be rendered directly using any utility or plane HTML page. Email Address and Mobile number are hashed.
Service Provider has to collect Email Address and Mobile number from Aadhaar number holders and perform below operations in order to validate the hash:
Mobile Number:

Hashing logic: Sha256(Sha256(Mobile+ShareCode))*number of times of last digit of Aadhaar Number

Example :
Mobile number: 9800000002
Aadhaar Number: 123412341234
Share Code: Abc@123
Sha256(Sha256(9800000002+ Abc@123))*4
In case if Aadhaar Number ends with Zero or 1 (123412341230/1) it will be hashed one time.
Sha256(Sha256(9800000002+ Abc@123))*1

Email Address:

Hashing Logic: This is a simple SHA256 hash of the email without any salt
Entire XML is digitally signed and Service Provider can validate the XML file using the signature and public key available on the UIDAI website.(https://uidai.gov.in/images/uidai_offline_publickey_26022019.cer).
