Simple decompression of 7z files using the Lzma SDKsometimes we only need to extract the LZMA algorithm compressed 7z files, sometimes need to extract on the embedded devices, using P7zip although supporting a variety of formats, but not easy to

Workaround One: Delete this node under the registry. Delete the Fipsalgorithmpolicy folder under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa or workaround two: 1, click Start, Run, type gpedit.msc, and then click OK. 2. Expand the

OrderIn the previous article, we introduced the most basic coding method--base64, and also briefly mentioned the principle of coding. This article continues to decrypt the series, of course, is also the introduction of a comparative basis of the

Encryption Algorithm Introduction HashHash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into
