WEP Key Generator. To generate a random WEP key, select the bit key length to generate and press the corresponding button; the ASCII or HEX key can then be copied to your clipboard manually or via the copy to clipboard button to the right of the generated key text field. You can also generate a custom WEP key based on your own pass phrase or other input. Using 32 hexadecimal digits vs ASCII equivalent 16-character password. An example when this is not the case is when you generate a 256 bit key, from which you derive a 128 bit key for 128-bit AES encryption. By unicode, I assume you mean UTF-8 (it's obvious that 16 UTF-16 characters can hold far more possible passphrases than 32 hex.

Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. Following is an online tool to generate AES encrypted password and decrypt AES encrypted password. It provides two mode of encryption and decryption ECB and CBC mode.

The SG WLAN Key Generator is a tool that allows for quick, valid, and strong WEP/WPA key generation. It uses the 94 standard ASCII characters (with codes 32 to 126) for maximum compatability. To generate a random WEP or WPA key, simply choose the desired key length and one will be generated for you. First, don't think of the MD5 hash as a character string but as a hex number. Therefore, each digit is a hex digit (0-15 or 0-F) and represents four bits, not eight. Taking that further, one byte or eight bits are represented by two hex digits, e.g. B'1111 1111' = 0xFF = 255. MD5 hashes are 128 bits in length and generally represented by 32 hex. Web app offering modular conversion, encoding and encryption online. Translations are done in the browser without any server interaction. This is an Open Source project, code licensed MIT. Encryption keys for AES are not expressed in characters or letters. Encryption keys are a series of 128 (or 256) bits. If you are using some kind of interface to enter a text-based password, internally it is turning your typed password into bits.

Usage Guide

Any plain-text input or output that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that text cannot be stolen.

For encryption, you can either enter the plain text, password, an image file or a .txt file that you want to encrypt. Now choose the block cipher mode of encryption. ECB(Electronic Code Book) is the simplest encryption mode and does not require IV for encryption. The input plain text will be divided into blocks and each block will be encrypted with the key provided and hence identical plain text blocks are encrypted into identical cipher text blocks. CBC mode is highly recommended and it requires IV to make each message unique. If no IV is entered then default will be used here for CBC mode and that defaults to a zero based byte[16].

The AES algorithm has a 128-bit block size, regardless of whether you key length is 256, 192 or 128 bits. When a symmetric cipher mode requires an IV, the length of the IV must be equal to the block size of the cipher. Hence, you must always use an IV of 128 bits (16 bytes) with AES.

AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. Things to remember here is if you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size. Now you can enter the secret key accordingly. By default, the encrypted text will be base64 encoded but you have options to select the output format as HEX too.

Similarly, for image and .txt file the encrypted form will be Base64 encoded.

Below is a screenshot that shows a sample usage of this online AES encryption tool.

AES decryption has also the same process. By default it assumes the entered text be in Base64. The input can be Base64 encoded or Hex encoded image and .txt file too. And the final decrypted output will be Base64 string. If the intended output is a plain-text then, it can be decoded to plain-text in-place.

But if the intended output is an image or .txt file then you can use this tool to convert the base64 encoded output to an image.

40-bit encryption refers to a key size of forty bits, or five bytes, for symmetric encryption; this represents a relatively low level of security. A forty bit length corresponds to a total of 2⁴⁰ possible keys. Although this is a large number in human terms (about a trillion), it is possible to break this degree of encryption using a moderate amount of computing power in a brute-force attack, i.e., trying out each possible key in turn.

Description[edit]

A typical home computer in 2004 could brute-force a 40-bit key in a little under two weeks, testing a million keys per second; modern computers are able to achieve this much faster. Using free time on a large corporate network or a botnet would reduce the time in proportion to the number of computers available.^[1] With dedicated hardware, a 40-bit key can be broken in seconds. The Electronic Frontier Foundation's Deep Crack, built by a group of enthusiasts for US$250,000 in 1998, could break a 56-bit Data Encryption Standard (DES) key in days,^[2] and would be able to break 40-bit DES encryption in about two seconds.^[3]

40-bit encryption was common in software released before 1999, especially those based on the RC2 and RC4 algorithms which had special '7-day' export review policies,^{[citation needed]} when algorithms with larger key lengths could not legally be exported from the United States without a case-by-case license. 'In the early 1990s ... As a general policy, the State Department allowed exports of commercial encryption with 40-bit keys, although some software with DES could be exported to U.S.-controlled subsidiaries and financial institutions.'^[4][5] As a result, the 'international' versions of web browsers were designed to have an effective key size of 40 bits when using Secure Sockets Layer to protect e-commerce. Similar limitations were imposed on other software packages, including early versions of Wired Equivalent Privacy. In 1992, IBM designed the CDMF algorithm to reduce the strength of 56-bit DES against brute force attack to 40 bits, in order to create exportable DES implementations.

Obsolescence[edit]

All 40-bit and 56-bit encryption algorithms are obsolete, because they are vulnerable to brute force attacks, and therefore cannot be regarded as secure.^[6][7] As a result, virtually all Web browsers now use 128-bit keys, which are considered strong. Most Web servers will not communicate with a client unless it has 128-bit encryption capability installed on it.

Public/private key pairs used in asymmetric encryption (public key cryptography), at least those based on prime factorization, must be much longer in order to be secure; see key size for more details.

As a general rule, modern symmetric encryption algorithms such as AES use key lengths of 128, 192 and 256 bits.
