Encrypting Passwords in ASP. Anybody can help me to write the function that can encrypt and decrypt this. To produce the same result as the vbscript code. A very simple XOR based encryption algorithm in VBScript. (VBScript) AES Encrypt and Decrypt a File. VBScript demonstrates how to AES encrypt a file of any size, and then decrypt.
This script is a sample encryption/decryption algorithm. The algorithm uses a encryption key and a random seed.
If you change the seed or the key, you will get a different encrypted string. You need to use the same key and seed for encryption and decryption '.
'. Script: encrypt.vbs '.
Purpose / Comments: '. Demonstrate a simple encryption algorithm.

Java Encrypt Decrypt
I just had the need for some Web-cookie encryption and discovered that neither of those encryption tips will work in VBScript due to the language's inexplicable lack of support for the Mid Statement. This revised function will work in VBScript. To encrypt put the text to be encrypted into the Text parameter and a string key in the Key parameter.
To decrypt do the same thing in reverse. <% Function CryptVBS(Text, Key) KeyLen = Len(Key) For i = 1 To Len(Text) KeyPtr = (KeyPtr + 1) Mod KeyLen sTxtChr = Mid(Text, i, 1) wTxtChr = Asc(stxtchr) wKeyChr = Asc(Mid(Key, KeyPtr + 1, 1)) CryptKey = Chr(wTxtChr Xor wKeyChr) hold = hold & CryptKey Next CryptVBS = hold End Function% Thanks, John. No fair getting a second shirt, but we appreciate your updating this encryption function. Did you like this tip? Why not let us know?
