There are a great deal of possibilities that you can look at. One that I have had one of the greatest experiences with is the Simple Directmedia Layer. It doesn’t come with a drag-and-drop graphics designer like Visual Studio (Is that what you mean by ‘UI designer’?). However its api is fairly powerful and as … Read more
You are reading the entire file at the start of the method: byte[] bytesToBeEncrypted = File.ReadAllBytes(file); This is causing the OutOfMemoryException. Here’s an idea of how you’d do this: static void EncryptFile(string file, string password) { byte[] passwordBytes = Encoding.UTF8.GetBytes(password); byte[] salt = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 }; … Read more
public class TranslateChar { /** @param args */ public static void main(final String[] args) { final Map<Character, Character> mapCharCod = new HashMap<>(36); final Map<Character, Character> mapCharDecod = new HashMap<>(36); mapCharCod.put(‘A’, ‘Z’); mapCharCod.put(‘B’, ‘X’); mapCharCod.put(‘C’, ‘Y’); mapCharDecod.put(‘Z’, ‘A’); mapCharDecod.put(‘X’, ‘B’); mapCharDecod.put(‘Y’, ‘C’); final String toCod = “CAB”; StringBuilder sb = new StringBuilder(“{“); for (final char c … Read more
You could use the AES Crypto Service Provider and then store the output as a binary string representation of the byte array output. I.e 12345 might encrypt into “1001001010110001” 4 solved Encrypt String (of only digits) into another String (of only digits)
Not sure I get your question right but my bet is you’re asking how to convert between ASCII and number representation of characters. Encoding/Decoding has nothing to do with RSA. You just use dynamic range shift. As the alphabet is in increasing order in ASCII so the only thing left is to offset the a … Read more
I think you miss some code here, cause that is not valid: // Read the decrypted bytes from the decrypting stream 2 solved Decrypt function is not working c# [closed]
The most space efficient way to store binary data is to store it as bytes. The only way you may get it even shorter is via compression. But for 92 Characters that will not amount to much. As for Base64: There are cases where we are forced to transmit binary data over a medium not … Read more
If the encryption method is an accepted standard method such as AES and the key is good it is not possible to find the key given the plain and encrypted data. If the encryption method is trivial such as Caeser Cipher then it can be found. If the key is trivial such as “password” or … Read more
have a command line option that says whether to encrypt or not crypttool [-e|-d] <file> solved plain text file or encrypted file(C programming)
Made it! After a long time of searching thanks to all you guys who answered this post i used the bouncy castle library and i’ve decrypt the desired String by doing the following: public static String decrypt(String valueToDecrypt) throws Exception { AESCrypt enc = new AESCrypt(); return new String(enc.decryptInternal(valueToDecrypt)).trim(); } private byte[] decryptInternal(String code) throws … Read more
You can use: maketrans–which allows creation of a translation table translate–applies translation table from maketrans to a string Code def encrypt(infile, outfile, translation): ”’ Encrypts by applying translation map to characters in file infile. ”’ # Create translation table table=””.maketrans(translation) # Apply table to all characters in input file # and write to new output … Read more
It seems the text is encrypted with the NULL encryption algorithm described in RFC 2410. If I run it through the accompanying decryption algorithm, it decrypts properly without error and gives the following plain text: OH0fRX0gOHZgOH0tOH4fRX8tOr0gOHZgOH0tOH4fOrZgOH0fRX8tOH4gOHZgOH0tOr4gRX8tOr4fRX0gOHZfOH4fRX4fOr0tOrZgOr4tObZgRX4fOr4tOrZeRX4fOrZfRX0fOH4tOH0gRX0fRX0fOrZeRX4gOH4tOr4gRX0gOr4tOH0fOrZfOH4fRX4tOr0fOH4gRX8tOr4fRX4fOHZgOr4fRX0gRX4fRX0tObZgRX4fOr4tOrZeRX4fOH4tOr0fOrZfOHZgOH4tObZgOr4fRX4tOr0fOrZgOH0tOr0gRX8tOHZgOH0tObZgOr0fRX4gOr4tOr0tOr4tOH0tObZgOr0gRX0gOHZfOr0tOr0fRX8tOr0gOrZgOH0tOr4tOH4tOHZfOr4tOr0fOH4gRX4gOr0fOrZfOH4gOr4tOr4gOrZfOH4fRX4gRX0gOrZgOH0fOr4tObZgOrZgOr0fRX4gOr4tOH4fOr4gRX0fOH4tOr0fRX4gOH0tOr4gOrZgOr4fOr0tOH0gOr4tOH0gOH0tOr4fOH0tOH0gOr4tOr0fOH4fRX4gOr0fOrZfOr0fRX4gOr4tOr0tOH0fRX4fOr0gRX4gOr0fOrZgOr4fOr0tOH4fOr4gRX0fOr4fOHZgOr4fOr0tOH4fOr4gRX4gOr0fOrZgRX4gOHZgOr4tOr4fRX0fOH0tOr4tOH4fOrZfOr4gOHZgOr4fRX4fOr0gRX4gOH0tOr0gOrZfOrZfOr4tOH4fOrZgOH4fRX0fOr4tOr4fOH0tOr4gRX0gOrZgOr0fRX4fOH0gRX0gOH0fRX0gOr0tOH4fRX0 The plain text does not make much sense to me, however.

Hashing is a one way process and Encryption is 2 way process. What I mean by this is , when we use a plain text and encrypt it to get a cipher text, we can again get the plain text from the cipher text. but that is not the case for hashing. You can never … Read more
You could use something like the following algorithm to accomplish this: // Our input string. String input = “I love fish”; // Contains the “encrypted” output string. StringBuilder encrypted = new StringBuilder(); // Process each character in the input string. for (char c : input.toCharArray()) { if (Character.toLowerCase(c) != ‘a’ && Character.isLetter(c)) { // If … Read more
Sender starts the handshake with server. Client starts handshake with server. Server generates a pair of Public and Private key using asymmetric encryption and re-encrypt the Public key alone using symmetric encryption. No. And passes the Public key to the sender. No. It sends its certificate to the client and they then start a secret-key … Read more
