An example of Java digital signature based on RSA algorithm

Original address: an example of Java digital signature based on RSA algorithmFirst, preface:Network data security includes the security of the data itself, the integrity of the data (to prevent tampering), the non-repudiation of the data source, and other elements. Encryption algorithm for data encryption can ensure the security of the data itself, the use of Mes

Implementation of non-symmetric encryption and digital signature RSA algorithm in Silverlight

RSA algorithm is the first algorithm that can be used both for data encryption and digital signature. It is easy to understand and operate, but also very popular. Its security is based on the difficulty of large integer factor factorization, and the large integer factorization problem is a famous problem in mathematics

Asymmetric encryption, SHA-1 encryption, Ras algorithm, Digital Signature
