RIPEMD128 (RACE Integrity Primitives Evaluation Message Digest) is a cryptographic hash function that generates a fixed-size message digest from input data. is a cryptographic function that generates a 128-bit output, known as a hash value. It was created by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel to enhance the RIPEMD-160 algorithm by providing faster performance while preserving a similar level of security. However, it is less commonly used when compared to other algorithms like SHA-256 and SHA-3.

There are a plethora of online RIPEMD-128 hash calculator tools available, so the best one for you will depend on your specific needs.

A retrospective overview of RIPEMD 128

The notation RIPEMD represents a group of distinct hash functions that are related to the MD-SHA-family. The first representative of this group was RIPEMD-0, which was recommended in 1992 by the European RACE Integrity Primitives Evaluation (RIPE) consortium. The compression function of RIPEMD-0 consists of two MD4-like functions that are computed in parallel, with 48 steps in total. 

However, early cryptanalysis by Dobbertin on a reduced version of the compression function indicated that RIPEMD-0 was a weak function, and this was later confirmed by Wang et al. who showed that a collision could be found for the full RIPEMD-0 hash function with as few as 216 computations.

In 1996, to address the cryptanalysis advances on MD4 and the compression function of RIPEMD-0, the original RIPEMD-0 was reinforced by Dobbertin, Bosselaers, and Preneel. This led to the creation of two stronger primitives, RIPEMD-128 and RIPEMD-160, which have 128/160-bit output and 64/80 steps, respectively. Two other less-known variants, RIPEMD-256 and RIPEMD-320 were also proposed, but they are claimed to have a security level equivalent to an ideal hash function with a twice smaller output size.
How is the RIPEMD 128 Hash Calculator useful?

RIPEMD is a set of cryptographic hash functions that are commonly used to create a condensed representation of a message or piece of data known as a message digest. Some of the main uses of RIPEMD include:

Verifying the integrity of data by comparing the computed message digest with the one provided by the sender, such as a downloaded file.

Creating digital signatures to verify the sender's identity and ensure the integrity of the message.

Using short hash values as keys for quick retrieval of records in database indexing

Securely storing passwords in databases by storing the hashed version of the password
Size of RIPEMD

The size of a RIPEMD hash depends on the specific version of the algorithm. The original RIPEMD algorithm generates a 128-bit hash, while the expanded version, RIPEMD-160, generates a 160-bit hash. The increase in the number of bits in the hash makes it more resistant to collision attacks. The output of RIPEMD-160 is always 20 bytes (160 bits) in size, regardless of the size of the input message.

LambdaTest is a popular cross-browser testing platform that allows developers to test their web pages and mobile applications on different browsers, devices and operating systems. With LambdaTest, you can perform automated browser testing using different frameworks like Selenium, Cypress, Playwright, and more.
 This helps to ensure that their pages and applications are compatible with different platforms. It also provides a variety of useful tools for developers. One such tool is the RIPEMD128 hash generator.

RIPEMD-128 is a tool for web developers and programmers that generates a checksum and hash for sensitive data, such as passwords and personal information. This free online utility encrypts the data by creating a 128-bit message digest from any amount of input.

To find the RIPEMD hash of a file, you can follow these simple steps:

1. Input the file into the "Enter Value" field.
2. Select "Calculate RipeMD128" from the drop-down menu.
3. The resulting hash will be displayed in the "Output" field.

The original RIPEMD algorithm generates a 128-bit hash, but it was later expanded to produce a 160-bit hash in RIPEMD-160, which increases the number of bits in the hash and makes it more resistant to collision attacks. The size of the RIPEMD-160 hash is 160 bits, which provides a high level of security as it is extremely difficult to find two different messages that produce the same hash. The size of the hash output is always 20 bytes (160 bits), regardless of the size of the input message.

Checking the hash of a downloaded file is a simple and efficient way to ensure that the file is safe and has not been tampered with. If the downloaded file is malicious or has been altered in any way, the resulting hash will differ from the one provided by the website. However, not all websites offer the option to check the file hash, and many people do not take the time to verify the integrity of their downloads.

Additionally, some websites use integrated driver signing or a Certificate Authority to sign their software, which allows the operating system to block the installation or execution of software that does not match an official signature. Even though these methods are intended to provide security, some people still prefer to cross-reference their software using a file hash generation and checking tool.

As for the security issues, the original RIPEMD algorithm with a 128-bit hash is still considered a secure hash function and is widely used, but for critical security concerns, more advanced hash functions such as RIPEMD-160, SHA-256, SHA-3, and BLAKE2 are recommended.
