Digital Certificate and its authentication process [reprinted], digital certificate reprinted As we all know, public key cryptography makes it easy to use digital signatures, encrypted communications, and other key services by using the public key and private key pair. The reason why public key technology can be widely used is that for entities that use the publi

would tell that the message really came from someone with a private key. The process of encrypting private keys is a digital signature.Data encrypted with the public key can only be decrypted by the private key, whereas the data encrypted with the private key can only be decrypted by the public key, and it is this asymmetry that makes the public-key cipher system widely used.2.2. AdvantagesCompared with symmetric key encryption, the advantage is that

enough. MD5 (RFC 1321) is an improved version of Rivest in 1991 for MD4. It still groups the input in 512 bits, and its output is 128 bits. MD5 is more complex than MD4, and is slower to calculate, but more secure. MD5 is not safe enough. SHA1 (Secure Hash algorithm) is designed by the NIST NSA, whose output is a Hash value of 160 bits in length, so it is better for anti-poor lifting. The SHA-1 design is based on the same principles as MD4 and mimics the algorithm. To improve security, the NIST

Preface First look at Baidu Encyclopedia of Digital Signatures and digital certificate interpretation: Digital Signature: A fixed-digit message digest is computed by the hash algorithm agreed by both parties. Mathematically guaranteed: As long as any one of the changes in the message, the recalculated report digest to the value will not match the original value.

Digital Image) An image can be defined as a two-dimensional function f (x, y). Here, X and Y are spatial coordinates, and in any coordinate (x, y) the amplitude F is called the brightness or gray scale of the image at the coordinate position. When the amplitude of X, Y, and F are finite discrete values, they are called digital images. Note that a digital image

Bob has two keys, one is the public key, the other is the private key. 2. Bob gave his public key to his friends----patty, Doug, Susan----each one. 3. Susan is going to write a confidential letter to Bob. When she finished, she used Bob's public key to encrypt it, and it was a secret effect. 4. When Bob
