Hello. What do you mean by your question? Do you need to create a digital signature? Here https://mysignature.io/thunderbird-signature-generator you can find recommendations on how to do it and also a special software that can do it for you. You can fill it with any personal information you want, including your photo. hope it is what you are looking for.

I know really little information about the importance of e-mail signature because I have never used it in my business but I will be really glad if you tell me about it

Dear Friend, --A digital certificate, an electronic document that contains the digital signature of the certificate-issuing authority, binds together a public key with an identity and can be used to verify a public key belongs to a particular person or entity. --A digital signature is an electronic signature which is used to authenticate the identity of the sender of a message or the signer of a document, and to make sure that the original content of the message or document that has been sent is unchanged. Digital signatures cannot be imitated by anyone else, and it has the ability to ensure that the original signed message arrived means that the sender cannot easily repudiate it late. --A digital signature certificate contains a public key as “certified” by a Certifying Authority (CA). some of the details of the certificate- -- 1. Version -- 2. Serial number -- 3. Signature Algorithm -- 4. Issuer -- 5. Valid From -- 6. Valid To -- 7. Subject -- 8. Public Key -- 9. CRL Distribution Point

DSC is Binary code that, like a handwritten signature, authenticates and executes a document and identifies the signatory. A digital signature is practically impossible to forge and cannot be sent by itself but only as a part of an electronic document or message.And digital signature is also a mathematical scheme for demonstrating the authenticity of a digital message or document.

A digital signature (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software, or digital document. Signatures are commonly used to authenticate documents. When you sign a physical document, you are authenticating its contents. Similarly, digital signatures are used to authenticate the contents of electronic documents. They can be used with PDF, e-mail messages, and word processing documents. To digitally sign a document, you must have a digital ID. This unique identifier can obtained from various certification authorities on the Web, such as VeriSign and EchoSign. Once you have a digital ID, you can add register it with programs that support digital signatures, such as Adobe Acrobat and Microsoft Outlook. Then you can use the program's "Sign" feature to add your digital signature to documents.

Hello friend "Digital Signature" A digital signature has the same function as that of a handwritten signature. But there is some technical concept involved in creating a digital signature. Digital signatures are an application of asymmetric key cryptography. Digital signatures enable the recipient of the information to verify the authenticity of the information’s origin, and also verify that the information is intact. Thus, digital signatures provide authentication and data integrity. A digital signature is superior to a handwritten signature in that it is nearly impossible to counterfeit, plus it attests to the contents of the information as well as the identity of the signer. The digital signature creation and verification process achieves the following legal requirements- ------- 1. Signer authentication ------- 2. Message authentication. ------- 3. Affirmative act. A digital signature certificate contains a public key as “certified” by a Certifying Authority (CA). some of the details of the certificate- -- 1. Version -- 2. Serial number -- 3. Signature Algorithm -- 4. Issuer -- 5. Valid From -- 6. Valid To -- 7. Subject -- 8. Public Key -- 9. CRL Distribution Points thanks

Hiiii friend,,,,,, DSC - Digital Signature Certificate ----------------------------------- - **A digital signature (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software, or digital document.** - Signatures are commonly used to authenticate documents.

They can be used with PDF, e-mail messages, and word processing documents. - To digitally sign a document, you must have a digital ID.

Once you have a digital ID, you can add register it with programs that support digital signatures, such as Adobe Acrobat and Microsoft Outlook. Then you can use the program's "Sign" feature to add your digital signature to documents. - The digital signature is simply a small block of data that is attached to documents you sign. It is generated from your digital ID, which includes both a private and public key. The private key is used to apply the signature to the document, while the public key is sent with the file. The public key contains encrypted code, also called a "hash," that verifies your identity. - Digital signatures can be used to certify or approve documents. Certifying signatures verify the document's creator and show that the document has not been altered since it was signed. Therefore, only the original creator of a document can add a certifying signature. Approval signatures can be added by anyone with a digital ID and are used to approve documents, track changes, and accept terms stated with a document. Regards, Jitendra Suthar

CONCEPT OF DIGITAL SIGNATURE Hi, To authenticate documents we use signatures. When we sign physical documents we authenticate its contents, in the same way digital signatures are used to authenticate the contents of electronic documents. They can be used for pdf files word processing and email messages. One must have digital ID to sign a document digitally This Digital ID can be obtained from various certification authorities. A small block of data that is attached to documents you sign is digital signature. Digital signature is generated from digital id which consists of both provate and public key. Digital signatures can be used to certify or approve documents. Thanks

A digital signature is practically impossible to forge and cannot be sent by itself but only as a part of an electronic document or message.And digital signature is also a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, and that the sender cannot deny having sent the message (authentication and non-repudiation), and that the message was not altered in transit (integrity). Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering Regards, Arjun PRatap Singh

HII A digital certificate, an electronic document that contains the digital signature of the certificate-issuing authority, binds together a public key with an identity and can be used to verify a public key belongs to a particular person or entity. A digital signature is an electronic signature which is used to authenticate the identity of the sender of a message or the signer of a document, and to make sure that the original content of the message or document that has been sent is unchanged. Digital signatures cannot be imitated by anyone else, and it has the ability to ensure that the original signed message arrived means that the sender cannot easily repudiate it late A digital signature can be used with any kind of message, whether it is encrypted or not, simply so that the receiver can be sure of the sender's identity and that the message arrived intact. A digital certificate contains the digital signature of the certificate-issuing authority so that anyone can verify that the certificate is real. Working Process Assume you were going to send the draft of a contract to your lawyer in another town. You want to give your lawyer the assurance that it was unchanged from what you sent and that it is really from you. You copy-and-paste the contract (it's a short one!) into an e-mail note. Using special software, you obtain a message hash (mathematical summary) of the contract. You then use a private key that you have previously obtained from a public-private key authority to encrypt the hash. The encrypted hash becomes your digital signature of the message. (Note that it will be different each time you send a message.) At the other end, your lawyer receives the message. To make sure it's intact and from you, your lawyer makes a hash of the received message. Your lawyer then uses your public key to decrypt the message hash or summary. If the hashes match, the received message is valid.
