| | Hi, I'm currently looking at password hashing and from what I've read so far, it seems pretty pointless. I read this [URL="http://phpsec.org/articles/2005/password-hashing.html"]article[/URL] which recommends using MD5 or SHA-1, however I Googled for decrypters and found them witin the first 3 results on Google. I don't quite understand the purpose of … |
| | Hey i wanted to know if there's a program that shows u a pattern on how they got the number if i give them 3 examples? for Ex: 1) 35777903801230601 (Encrypted) = 46071642 (Decrypted) 2) 35777903248036801 (Encrypted) = 43975216 (Decrypted) 3) 35777903508068601 (Encrypted) = 91756761 (Decrypted)  |
| | I am working for encryption and decryption using rsa algorithm ,and adding my own concept in rsa, after rsa and padding i m getting a string like- 100011234A12300A12A231A234A981A for different input output string is increase... Is there any technique by use of that i can compact this string [ then … |
| | I'm attempting to create a one line Caesar cipher decryption program in python and i'm afraid i've come to the end of my knowledge and well past it. this is the closest working code i've got: [code]def test3(): print("The decrypted text is: "+"".join(map(lambda x: chr(ord(x)+y),x)))[/code] as you can see it … |

I have looked at the [URL="http://en.wikipedia.org/wiki/RC4"]wikipedia page[/URL] for RC4, and I'm trying to adapt that algorithm to my problem. I can get the correct encrypted text when I just cout the values. However, when I try … |
 | This is my Cogwheel Encryption Method to encrypt and decrypt strings. Wheel1 is Replace by Wheel2 when Encrypting and Wheel2 is Replace by wheel1 when you are decrypting... To Encrypt a string, just call the EncryptString function [CODE=vb] Text2.Text = EncryptString(Text1.Text) [/CODE] To Decrypt a string, just call the DecryptString …  |
| | Hello. I am currently working on a little password based file encryption feature for an application I am doing. The following is an incomplete function that I have worked on to encrypt some content and (will eventually) write it to a file. [CODE]public static void encrypt(byte [] data, char [] …  |
| | The program initially asks the user to insert the secret sentence and the encryption code (an integer number in the range 1-100). Then, the program calls a user-defined function void encrypter (char *, int) that accepts the string pointer and the encryption code. The encryption algorithm is based on the … |
| | Hello! I have i problem i was hoping you could help me with, I have to write a script that will ask the user for a username and password, and validate it through /etc/passwd and /etc/shadow. I've looked all over the place for an answer to this and i just … |
| | Back in 1976, along with Stanford University professor Martin Hellman, Whit Diffie produced quite possibly the most important paper in the history of cryptography. That paper, New Directions in Cryptography, laid the groundwork for solving one of the fundamental problems of cryptography, that of key distribution. Now Diffie himself is …  |
| | I installed flycryptor software on my system to lock certain files and folders. Now the problem is that those files are encrypted and my friend have uninstalled the software .Those files appear somewhat scary to look at and are not opening properly. So is there any way by which i …  |
