Method Sharing: Users simply open the latest version of the mobile phone client, click the camera icon, select the "Package Perspective" option, scan the package two-dimensional code can be. Currently, the perspective function only supports the iOS system, and, for security reasons only, the order payer is open. The new feature is part of Amazon's "Black Friday" promo

with the same primary key hash value share the same partition in DynamoDB, the local level two index contains only items that are stored in the same location (the same partition). Therefore, LSI can be used to query items that have the same primary key hash value, but with different range keys.It is important to note that all the GSI related to the table must be specified when the table is created. A GSI index does not require that indexed properties be unique. The GSI supports eventual consist

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.

Http://www.cnblogs.com/1-2-3/archive/2007/09/17/colloquialism-digital-certificate-part1.htmlSummaryThis series is easy to read, so you can understand the basic principles of digital signatures and how to apply them (even if you are an enterprise boss who is not computer savvy, you can read this article). Then we step into the technical details, and finally will give a B/s information system using the

OrderRecent work has been around the digital certificate, the understanding of CA certificate is a little bit, but not so deep, now to use this aspect of things, obviously still a little lacking, then from this beginning, I will my own study, work history with everyone to share, I hope to understand the CA The certificate of the children's shoes is helpful.Obviously, this article is mostly a theoretical introduction, followed by a number of relevant e
