Java encryption and DSA Digital Signature Bromon 1. One-way encryption (MD5 and SHA-1) One-way encryption is usually used for message summarization. The specific algorithm can be obtained by reading the source code of Java. Security. After encapsulation, you can use a simple static method to implement it. Look: Package org. bromon;Public class md5encoder{Public static void main (string ARGs []){String info = ARGs [0];Try{// Select the MD5 Encryption

Third-party libraries such as OpenSSL were compared, and Cryptopp was used.1. source File CollationYou can get the source files of the library in http://www.cryptopp.com/, and then archive the files again after extracting them. The header file is placed in the Include folder and the CPP is placed in the SRC di

1. Overview of Asymmetric encryption algorithmsAsymmetric encryption algorithm is also called Public key algorithm, which solves the problem of symmetric encryption algorithm key distribution, the basic features of asymmetric encryption algorithm are as follows:1. Encryption key and decryption key are different2. A key in the key pair can be exposed3, according to public key difficult to calculate the private keyAccording to the characteristics of asymmetric encryption algorithm, user digital si

1. DSA-Interface Specification The DSA bus is an asynchronous and bidirectional communication bus designed internally for communication between a group of two microprocessors. It has three bidirectional lines: ● Data-start synchronization and Data Transmission ● STB-data Election (data is valid when STB Is low) ● Ack-start synchronization, data transmission, confirmation and communication response
