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

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.

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 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.

Simple tool sha3 (512, 384, 256, 224) strings for the text content online. SHA-3 is the winner of a five-year competition to select a new cryptographic hash algorithm where 64 competing designs were evaluated. Each of the SHA-3 functions is based on an instance of the Keccak algorithm, which NIST selected as the winner of the SHA-3 competition, but those SHA-3 functions won't produce hashes identical to Keccak.

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.
