AES Encrypt / Decrypt
by free-tools.io Executed 619 times

Simple tool to encrypt and decrypt using AES. The Advanced Encryption Standard (AES) is a U.S. Federal Information Processing Standard (FIPS). It was selected after a 5-year process where 15 competing designs were evaluated. This tool supports AES-128, AES-192, and AES-256. It will pick the variant by the size of the key you pass in. If you use a passphrase, then it will generate a 256-bit key.

RC4Drop Encrypt / Decrypt
by free-tools.io Executed 98 times

Simple tool to encrypt and decrypt using RC4Drop. It was discovered that the first few bytes of keystream are strongly non-random and leak information about the key. We can defend against this attack by discarding the initial portion of the keystream. This modified algorithm is traditionally called RC4-drop. By default, 192 words (768 bytes) are dropped by this tool.

Simple tool md5 strings for the text content online. MD5 is a widely used hash function. It's been used in a variety of security applications and is also commonly used to check the integrity of files. Though, MD5 is not collision resistant, and it isn't suitable for applications like SSL certificates or digital signatures that rely on this property.
