Signature-2

The legal community and civilization in the process often requires us to sign - sign-in session, approved documents, the application agreements, contracts, statements, bills, credit cards, receipt, letter, the commission, and so agents can not be separated from the signature. Signed in particular international importance, has not personally signed the documents, documents are often ineffective. As China in various fields into line with the international community, the seal will gradually withdraw from the economic arena, is no longer Pingxin legal proceedings. Signed in the use of the frequency increasing, a good sign more than seal the security role.

With the rapid socio-economic development and people's living standards rising, the paperless office trends are becoming evident, it is the opportunity to put pen to paper to write on the decline. The author has always been closely linked with pen, paper and writing skills and we are slowly opening to alienate. But no matter when, there can not be the words "hand release", and that is signed. Is the signature of a person in the social, legal, contractual provisions, such as the relationship of all, on behalf of the personal credit and personal aesthetic taste of visual signs, also known as signature, signed.

QQ signature use

QQ signature

QQ signature use of a signature expression of personality, some people usually use the signature file to record some of the files, such as a good friend of the QQ number, phone number and so on. Signed in accordance with the type of style can be divided into: Co-signed the text, Even the pen to sign, Interesting sign, Official sign, Business sign. QQ signature expression signatures in addition to the use of the personality, often used for commercial purposes or to guide the company's Web site.

Pen even co-signed the text

Pen even co-signed the text

Wen is to co-sign the names of characters from stroke to reduce the very few, usually more than a "shared" stroke, or the names of the two components of a single word or words to closely linked with a high concentration of Design style. Co-signed the text more difficult to identify, but by a point, that is, suddenly, very artistic taste. Co-signed the text is a Chinese folk art of the signature characteristics. Zhao Ji Huizong from "the world is a" sign, and Ming Zhu were seized by the "monogram" sign, Qian Zhongshu to the modern, wood, and other famous Tang San signatures, we can see that co-signed the text of the Law for a long time, not long Decline, has become a very popular signature techniques. There are co-signed the text of the following combinations: symbiotic, shared by pen, compatible, inclusive.

The digital signature encryption and decryption process

The private key encryption and decryption process that uses public key system, but the process to achieve just the opposite, use of different keys. The use of digital signatures is the sender's key right, to send in their own private key encryption, the sender with the recipient's public key to decrypt. This is a one-to-many relationship: have any sender's public key can verify the validity of digital signatures, while the private key encryption is used to decrypt the receiver is the key, which is many-to-one Relationship: know that any recipient's public key can send encrypted to the recipient, only to receive only one side of the private key can decrypt the information. In practical, usually a user has two keys right, one of the key used to decrypt encrypted digital signature, a key used to encrypt private key to decrypt. This approach provides higher security.

RSA digital signature algorithm

RSA digital signature algorithm is actually through a hash function to achieve. The digital signature feature is that it represents the characteristics of the document, if the document changed, the value of the digital signature will also change. The document will be different in different digital signature. One of the most simple hash function is to document the accumulation phase binary code, the last of a number of places. Hash function to send data on the two sides are open only by adding digital signatures and authentication in order to achieve genuine public safety network transmission.

The main way of digital signatures

Application of a wide range of digital signatures in three major ways, that is: RSA signature, DSS signature and the signature Hash. The three algorithms can be used alone, or combined use. Digital Signature Algorithm password through the data increases, the realization of the decryption transform with DES to count, RSA digital signature algorithm can achieve. However, there are three more or less technical defect, or not mature.

Digital signature and signed a written document similar

Use of digital signatures, but also to confirm the following two points: first, the message is sent by the signer; Second, the information received from the issuance date has not been any changes. This digital signature can be used to prevent electronic information easily modified as a result of which was fake, or fraudulent use of the name of other people send a message. Or sent (received) a letter and then be denied to happen, and so on.

Digital signature is based on public key system

Digital signature is based on public key system

Digital Signature is a public-key encryption technology, the other applications. Its main way that the message from the sender of the message text to generate a 128-bit hash value (or message digest). To send in their own private key of the hash value is encrypted to form a sender's digital signature. Then, the digital signature will serve as a message of the Annex and the message to send to the recipient of the message. The message from the first recipient to receive the original message out in 128-bit hash value (or message digest), and then re-use sender's public key to the message attached to the digital signature to decrypt. If the two hash values of the same, then the recipient will be able to confirm the digital signature is the sender. Can be achieved through the digital signature on the identification of the original message.

The digital signature method

Digital signatures are a lot of ways, the current use of digital signatures is more public-key encryption technology, such as RSA Date Security based on the company's PKCS (Public Key Cryptography Standards), Digital Signature Algorithm, x.509, PGP (Pretty Good Privacy). In 1994 the United States Institute of Standards and Technology published the Digital Signature Standard by the wider use of public key cryptography. Public key encryption system used in non-symmetric encryption algorithm.

Digital Signature

In short, the so-called digital signature is attached to a unit of data on some of the data, or data on the unit by changing the password. Such data or transform data unit to allow the recipient to identify the source of the data unit and data unit and protect the integrity of the data to prevent people (for example, the recipient) for forgery. It is a form of electronic messages signed a way to sign a message in a communication network transmission. Based on public-key cryptosystem and private key cryptography have access to digital signatures, currently mainly based on public key cryptography digital signature. Including the general and special digital signature digital signature. There are ordinary digital signature algorithm RSA, ElGamal, Fiat-Shamir, Guillou-Quisquarter, Schnorr, Ong-Schnorr-Shamir digital signature algorithm, Des / DSA, Elliptic Curve Digital Signature Algorithm and finite automata, such as digital signature algorithm. A special digital signature blind signature, proxy signature, group signature, the signature can not be denied a fair blind signature, the signature threshold, with a message recovery signature, and so on, and it is closely related to the specific application environments. It is clear that the application of digital signatures the legal issues involved, the U.S. federal government based on the limited domain of the discrete logarithm problem has developed its own Digital Signature Standard (DSS). Some countries such as France and Germany have developed a digital signature law.

signature

Signed, including its name, the amount and type of parameters, it's the type of return (if any), as well as their calling convention (or default vararg). Signed attributes and methods similar to the signature. Local variables of the field and they are just the type of signature

Signed for what you Signed

Free art knowledge of a good sign for what you? Some would say that good people will sign more self-confidence; some people would say that would be a very good sign face; also say that good The signature is an art to enjoy. Yes, these are the signatures of the review. A good sign that we will bring a lot. Is not just a few more.

No matter what you do, I feel good, work on Shun, the business market will naturally increase the success rate. On the other hand, in a bad mood, irritability, Banshenmeshi is not shun, and can easily go wrong. The same signature, signature, if well written, was also pleased to see their own. When you sign in public free and easy, beautiful signature, and has won praise and envy of people around the eyes, then you will feel, how are we doing? Do not ask, is certainly the Mei Zizi. Therefore, we either star or individuals, there is a good sign or very important. Would be a good sign with our lives. Good practice their own signature, the signature does not have its own friends, quickly design one.
