View 1 Repliesi have created a encrypted string to match with a target string to pass it along with client URL for authentication. it doesn't match. here is an algorithm used to create a encrypted string.
text = "astringtobeencrypted";
string strglobalkey = "mytestglobalkey";
string hexivkey = "testing12345";
ebCryptLib.eb_c_Cipher ci = new ebCryptLib.eb_c_Cipher();
string strhex1 = ConvertStringToHex(strglobalkey);
string strhex2 = ConvertStringToHex(hexivkey);
byte[] bytes = (byte[])ci.EncryptStringRaw(EB_CRYPT_CIPHER_ALGORITHM.EB_CRYPT_CIPHER_ALGORITHM_DES3_ECB,
strhex1, strhex2, text);
return Convert.ToBase64String(bytes);
the above alogithm returns a string which doesn't match with our targetted string provided by the client.
what should i do to match with the targetted string? The client had generated the encrypted string using PHP.
I have a 15 digit string to encrypt.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.
I encrypt and decrypt a string with a private key and following functions. so I encrypt a string with Encrypt function and decrypt the encrypted string with decrypt function. If someone can change the encrypted string and then it decrypts with decrypt function, the decrypted string isn't equal to plain text before encrypting. I want to know how can I check is decrypted string equals to plain text before encrypting?

I have a Perl script that calls aspnet_compiler.exe to compile a large ASP.NET website. The problem is that it takes very long to run. Is there any way to compile just a single .aspx file from the command line? (I think that would suit the needs of my script) It seems that all aspnet_compiler.exe can do is compile at a directory level.
