Simple and practical method for web. Config encryption and decryption

Web. most of the config files do not need to be seen by others. The following provides an encryption and decryption Statement, which is concise, convenient, and practical. First, you can see the effect, as for the principles of encryption, I have made a lot of instructions on other web pages. Here I will only demonstrate the effect. <ConnectionStrings> <add name = "SQLConnString1" connectionString = "server = WJW-PC \ SQL2008; user id = sa; password = 12345; Initial Catalog = dbFASH; min pool size = 4; max pool size = 400; "/> <add name =" eziyaConnectionString1 "connectionString =" Data Source = HOME-COMPUTER; Initial Catalog = dbFASH; integrated Security = True; MultipleActiveResultSets = False; Packet Size = 4096; Application Name = & quot; Microsoft SQL Server Management Studio & quot; "providerName =" System. data. sqlClient "/> <add name =" eziyaConnectionString2 "connectionString =" Data Source = 192.168.1.200; Initial Catalog = dbFASH; Persist Security Info = True; User ID = taoka; MultipleActiveResultSets = False; packet Size = 4096; Application Name = & quot; Microsoft SQL Server Management Studio & quot; "providerName =" System. data. sqlClient "/> <add name =" eziyaConnectionString3 "connectionString =" Data Source = 192.168.61.160; Initial Catalog = dbFASH; Persist Security Info = True; User ID = sa; MultipleActiveResultSets = False; packet Size = 4096; Application Name = & quot; Microsoft SQL Server Management Studio & quot; "providerName =" System. data. sqlClient "/> </connectionStrings> Node Code of the encrypted connectionStrings <connectionStrings configProtectionProvider =" RsaProtectedConfigurationProvider "> <EncryptedData Type =" http://www.w3.org/2001/04/xmlenc# Element "xmlns =" http://www.w3.org/2001/04/xmlenc# "> <EncryptionMethod Algorithm =" http://www.w3.org/2001/04/xmlenc# Tripledes-cbc "/> <KeyInfo xmlns =" http://www.w3.org/2000/09/xmldsig# "> <EncryptedKey xmlns =" http://www.w3.org/2001/04/xmlenc# "> <EncryptionMethod Algorithm =" http://www.w3.org/2001/04/xmlenc# Rsa-1_5 "/> <KeyInfo xmlns =" http://www.w3.org/2000/09/xmldsig# "> <KeyName> Rsa Key </KeyName> </KeyInfo> <CipherData> <CipherValue> keys + keys/j + YCvH/r6ABoE/queues/W7f7Wkqj + FDwse + keys + p5Apf0E = </CipherValue> </CipherData> </EncryptedKey> </KeyInfo> <CipherData> <CipherValue> s3PKarSQ/tlnG5YcE/z/KLbnSLljw/nOj + signature + OM3f0WOh57evnW Examples/5 CTCGfZ/k0u + jWAGYYuOxlT6/examples + d3itc + h + examples + IulmOYWEnp2xwC + Sm/examples // examples/examples + samples + xRFT9btNWm/examples + 5cp + oISOyMMkFYvzCs TKpYYYwQ/xW/samples + aPLyPrBjsVddfnO/samples/I4/Vb7vsX2VoaFc0BrMxzYe6z/samples/5/N46gofk7g/W/samples/Samples Response + response/response // response + 0HLAsBsPzLRrppHyFMqIBuNe1iWxBM + j3PQUeN + oXJog79YoFxdd4cf1 + jMZn0 + ee7aOvEu4WGv3 Lost/n/MsLpVJmJTzA + lost/71cBSE8KSLOj/aGf2p4UBSUPRk = </CipherValue> </CipherData> </EncryptedData> </connectionStrings> the connection information is completely invisible! Below are two. bat batch file encryption: @ echo off C: \ WINDOWS \ Microsoft. NET \ Framework \ v2.0.50727 \ aspnet_regiis.exe-Arg "connectionStrings" "E: \ code \ proj \ Web" decryption: @ echo off C: \ WINDOWS \ Microsoft. NET \ Framework \ v2.0.50727 \ aspnet_regiis.exe-pdf "connectionStrings" "E: \ code \ proj \ Web" PAUSE directly copy the statement. in the BAT file, E: \ code \ proj \ Web is the corresponding web. the path of config, which can only be operated on one computer; otherwise, it is irreversible.
