RandomKeygen is a free mobile-friendly tool that offers randomly generated keys and passwords you can use to secure any application, service or device. KEY RandomKeygen - The Secure Password & Keygen Generator.

HMAC(Hash-based message authentication code) is a message authentication code that uses a cryptographic hash function such as SHA-256, SHA-512 and a secret key known as a cryptographic key. HMAC is more secure than any other authentication codes as it contains Hashing as well as MAC.

Below is a free online tool that can be used to generate HMAC authentication code. We can generate hmac-sha256 as well as hmac-sha512 code with it.

• When the key is changed the prefix of sha1(key) function is automatically filled in the IV field. You still may change the IV. The feature is intended only for your convenience. Using the radio buttons under the Key input field, you can specify whether the entered key value should be interpreted as a plain text or a hexadecimal value.
• Like DES before it, AES was awarded FIPS status. The US government considers all AES key sizes to be sufficient for classified information up to the 'Secret' level, with 'Top Secret' information requiring AES-192 or AES-256. AES has now entirely replaced DES worldwide as the default workhorse symmetric encryption standard.

Usage Guide - HMAC-SHA256 Online Tool

First, enter the plain-text and the cryptographic key to generate the code. Then, you can use select the hash function you want to apply for hashing. The default is SHA-256. Then you can submit your request by clicking on the compute hash button to generate the HMAC authentication code for you.

By default, the output is in plain-text format but you also have an option to get the output in Base64 format. Below is a screenshot of the usage:

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.

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. /how-does-amazon-generate-game-keys.html. 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. Civilization 4 mac demo download.
