AES Encrypt / Decrypt

by free-tools.io Executed 3,680 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.

DES Encrypt / Decrypt

by free-tools.io Executed 490 times

Simple tool to encrypt and decrypt using DES. DES is a previously dominant algorithm for encryption, and was published as an official Federal Information Processing Standard (FIPS). DES is now considered to be insecure due to the small key size.

MD5 Hash Generator

by free-tools.io Executed 295 times

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.

PBKDF2 Hash Generator

by free-tools.io Executed 448 times

Simple tool PBKDF2 strings for the text content online. PBKDF2 is a password-based key derivation function. In many applications of cryptography, user security is ultimately dependent on a password, and because a password usually can't be used directly as a cryptographic key, some processing is required. A salt provides a large set of keys for any given password, and an iteration count increases the cost of producing keys from a password, thereby also increasing the difficulty of attack.

RC4 Encrypt / Decrypt

by free-tools.io Executed 102 times

Simple tool to encrypt and decrypt using RC4. RC4 is a widely-used stream cipher. It's used in popular protocols such as SSL and WEP. Although remarkable for its simplicity and speed, the algorithm's history doesn't inspire confidence in its security.

RC4Drop Encrypt / Decrypt

by free-tools.io Executed 232 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 sha1 strings for the text content online. The SHA hash functions were designed by the National Security Agency (NSA). SHA-1 is the most established of the existing SHA hash functions, and it's used in a variety of security applications and protocols. Though, SHA-1's collision resistance has been weakening as new attacks are discovered or improved.
