基于QR(Quick Response)码自定义加密解密算法的电子签章技术,对明文进行加密后快速生成二维码完成对设计蓝图的审核签章,利用Android平台进行二维码的快速扫描并解密展示签章内容。根据选择不同的编码集,系统自动调整加密算法产生不同复杂程度的密文形成二维码签章,Android扫描二维码后调用相应的解密程序进行签章解密。实践证明,该加解密算法在实际项目运用性能优越,稳定便捷,二维码辨识度高,应用效果非常好,使得规划设计领域的电子签章审核越来越便携实用,并已在规划设计类企业中得到应用。
Based on QR (Quick Response) code custom encryption and decryption algorithm of electronic signature technology, the plaintext encryption quickly generate two-dimensional code to complete the design blueprint audit signature, the use of Android platform for fast scanning and decryption of two-dimensional code display Signed content. According to different coding sets, the system automatically adjusts the encryption algorithm to generate two-dimensional code signatures of different complexity of ciphertexts. After scanning the two-dimensional code, Android calls the corresponding decryption program to perform signature and decryption. Practice has proved that the encryption and decryption algorithm in the actual project performance superior, stable and convenient, two-dimensional code recognition is high, the application effect is very good, making planning and design of electronic signature audit more and more portable and practical, and has been in the planning and design category Get applied in the enterprise
