Padding For Aes 256 Bit Key Generator
Generate a random 128-bit key (k1), a random 128-bit IV, and a random salt (64 bits is probably sufficient). Use PBKDF2 to generate a 256-bit key from your password and the salt, then split that into two 128-bit keys (k2, k3). Make sure your algorithm's native output is at least 256 bits, or this will be slow. PBKDF2-SHA256 is a good choice. 256-bit encryption is fairly standard in 2019, but every mention of 256-bit encryption doesn’t refer to the same thing. Sometimes 256-bits of encryption only rises to a security level of 128 bits. Sometimes key size and security level are intrinsically linked while other times one is just used to approximate the other.
In the method of getRawKey, it uses SHA1PRNG to generate random paddings to make the AES key to 256-bit size which is different from the iOS implementation (it uses zeroes to pad the key to 256-bit). 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. The AES algorithm is defined in the FIPS standard with keylenght of 128, 192 or 256 bits. So you cannot use directly a 56-bit key. One needs to have a key with the proper length to use the AES encryption algorithm. Data will be protected using AES-256 encryption with a 56-bit effective key length.

- AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm. The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen. AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits.

Implementation for php 7.x was added
As you see this implementation is using openssl instead of mcrypt and the result of the encryption/decryption is not compatible with each other.
The mcrypt function will be deprecated feature in PHP 7.1.x
What is AES encryption?
It is a webtool to encrypt and decrypt text using AES encryption algorithm. You can chose 128, 192 or 256-bit long key size for encryption and decryption. The result of the process is downloadable in a text file.
How to use AES encryption?
If you want to encrypt a text put it in the white textarea above, set the key of the encryption then push the Encrypt button.
The result of the encryption will appear in base64 encoded to prevent character encoding problems.
If you want to decrypt a text be sure it is in base64 encoded and is encrypted with AES algorithm!
Put the encrypted text in the white textarea, set the key and push the Decrypt button.
When is helpful to use AES encryption?
When you want to encrypt a confidential text into a decryptable format, for example when you need to send sensitive data in e-mail.
The decryption of the encrypted text it is possible only if you know the right password.

How secure is AES encryption algorithm?
AES encryption is used by U.S. for securing sensitive but unclassified material, so we can say it is enough secure.
Encryption Key Generator 128 Bit
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. 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. Windows generate ssl certificate and key.
