First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM)

Reproduced in http://www.xdty.org/1678 In the project you need to add a registration function, think of using RSA Asymmetric encryption method. Third-party libraries such as OpenSSL were compared, and Cryptopp was used.1. source File CollationYou

Objective The first two articles simply implement blockchain creation and proof of workload, but they are all in memory. The actual blockchain should be stored permanently, which makes sense. A permanent blockchain storage is started

1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

Trading Mechanism:1. Blockchain can store transaction results safely and reliably2, in the blockchain, once the transaction is created, no one can modify or delete3, the transaction by some input and some output combination4. For a new transaction,

Bufio implements buffered I/OBytes provides functions for byte slicing.Crypto collects common encryption ConstantsErrors implements the function with incorrect operationsExpvar provides a standard interface for public variables, such as the
