512 Bit Encryption Key Generator
RSA(Rivest-Shamir-Adleman) is an Asymmetric encryption technique that uses two different keys as public and private keys to perform the encryption and decryption. With RSA, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the encrypted message. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH, etc.
Oct 20, 2015 Breaking 512-bit RSA with Amazon EC2 is a cinch. To break 512-bit RSA encryption keys has plummeted to an all-time low of just $75 and four hours using a recently published recipe that even. 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. RSA encryption usually is only used for messages that fit into one block. A 1024-bit RSA key invocation can encrypt a message up to 117 bytes, and results in a 128-byte value; A 2048-bit RSA key invocation can encrypt a message up to 245 bytes. The improved AES algorithm that use 512 bit of key and data block provides high level of security, because of the use of key size larger by four times than the original 128-bit AES key. AES-256 requires a 256bit key. SHA-512 will output 512 bits so unless you chop off half of the digest it will not work. A better solution is to use a standard and well tested key derivation function such as pbkdf2. Don't roll your own crypto unless absolutely necessary.
AES encryption is a web tool to encrypt and decrypt text using AES encryption algorithm. The tool is free, without registration.
Aes 512 Bit Encryption
Below is an online tool to perform RSA encryption and decryption as a RSA calculator.
For Java implementation of RSA, you can follow this article.
First, we require public and private keys for RSA encryption and decryption. Hence, below is the tool to generate RSA key online. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded.
By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format.

Below is the tool for encryption and decryption. Either you can use the public/private keys generated above or supply your own public/private keys.
Any private or public key value that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that private keys cannot be stolen.

This tool provides flexibility for RSA encrypt with public key as well as private key along with RSA decrypt with public or private key.
Openssl generate rsa key pair. If you’re the only one that uses the computer, this is safe.

Usage Guide - RSA Encryption and Decryption Online
In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit click on the button. This will generate the keys for you.
For encryption and decryption, enter the plain text and supply the key. As the encryption can be done using both the keys, you need to tell the tool about the key type that you have supplied with the help of radio button. By default, public key is selected. Then, you can use the cipher type to be used for the encryption. The different cipger options are RSA, RSA/ECB/PKCS1Padding and RSA/ECB/OAEPWithSHA-1AndMGF1Padding. Now, once you click the encrypt button the encrypted result will be shown in the textarea just below the button.
Remember, the encrypted result is by default base64 encoded.
Similarly, for decryption the process is same. Here, you need to enter the RSA encrypted text and the result will be a plain-text. You have both options to decrypt the encryption with public and private keys.
