Difference Between Cisco HMAC SHA 1 and HMAC SHA 1 96 (With Table)

Hashing methods are as safe as the mathematical function, but what counts later is the bit length, which should be as large as possible to avoid collisions (multiple inputs ending up with the same hash output). SHA1 and SHA1-96 calculate identical 160-bit hash results; the difference is that SHA1-96 truncates and embeds a 96-bit hash value in the packet.

Cisco HMAC SHA 1 vs HMAC SHA 1 96

The main difference between Cisco HMAC SHA-1 and HMAC SHA-1 96 is that Cisco HMAC SHA-1 is a more basic form of the hash, generating a shorter code with fewer unique combination possibilities, while HMAC SHA-1 96 generates a longer, and therefore more complicated, hash. Since 2015, SSL certificates based on SHA-1 have been phased out. By 2016, all new certificates were required to use SHA-196. Certain earlier certificates, on the other hand, remain valid, which is why SHA-1 is being used today.

The Secure Hashing Algorithm – 1 is another name for the cryptographic hash function SHA-1. This algorithm is a Federal Information Processing Standard in the United States. As an input, SHA-1 creates a 160-bit “message direct,” also known as a sha1 hash key (20-byte). This is often shown as a hexadecimal value with a length of 40 characters.

The SHA-1 algorithm family, which includes HMAC SHA 1 96, is a member of the secure hashing algorithm 196, sometimes referred to as HMAC SHA 196. The cryptographic hash function uses a sequence of mathematical operations on digital data to generate the hash. After SHA-1, this hashing algorithm was the most widely employed. 512-bit or 64-byte chunks of data are used in this method. Once the encryption key is generated, it produces the hash value 196. (which, as the name suggests, has 196 bits).

What is Cisco HMAC SHA 1?

Cisco HMAC SHA-1 is a mathematical cryptographic hash function which is also known as the Secure Hashing Algorithm – 1. This algorithm is a Federal Information Processing Standard in the United States. As an input, SHA-1 creates a 160-bit “message direct,” also known as a sha1 hash key (20-byte). This is often shown as a hexadecimal value with a length of 40 characters.

SSL, TLS, S/MIME, and a slew of other security protocols and applications utilize this approach. This method is a Federal Information Processing Standard in the United States, developed in 1995 by the US National Security Agency. This secure hashing technique is mandated by law for use in certain US government protocols and applications to safeguard sensitive data. In addition, systems like Monotone and Git utilize it to verify the integrity of the data. They mostly use it to detect data corruption rather than maintain security. Certificate authorities have preferred to use this algorithm since it was created (CAs).

In February 2017, Google and CWI Amsterdam used the SHA-1 method to create two different PDFs that produced the same hash key. This was the first time the algorithm has faced a collision attack. However, for HMAC, it was shown to be very safe (hash-based message authentication code).

What is HMAC SHA 1 96?

A secure hashing method known as HMAC 1 96, often known as the 1 96-bit SHA-1 algorithm, is a member of the SHA-1 algorithm family. The cryptographic hash function uses a sequence of mathematical operations on digital data to generate the hash. After SHA-1, this hashing algorithm was the most widely employed. 512-bit or 64-byte chunks of data are used in this method. Once the encryption key is generated, it produces the hash value 196. (which, as the name suggests, has 196 bits).

After the collision of the secure hashing algorithm-1, this is the most frequently used hashing protocol. It’s widely advocated for usage in a variety of cryptocurrencies, the most popular of which being bitcoin. It validates transactions and calculates proof of work and stake in cryptocurrencies using this hash. It performs the proper level of password hashing in addition to verification and computation. As a result, Linux and Unix software manufacturers are already using this hashing technique in their password security solutions. It’s being considered for DNSSEC implementation (Domain Name System Security Extensions).

There are six different hash functions in this algorithm, and they all have the same hash value. This method is sometimes referred to as a family of algorithms because of this. Novel hash functions include the SHA-256 and SHA-512 algorithms.

Main Differences Between Cisco HMAC SHA 1 and HMAC SHA 1 96

  1. Cisco HMAC SHA1 is the first version of SHA and produces a hash value of 160 bits whereas, HMAC SHA 1 96 is a variant of SHA2 that produces a hash value of 196 bits.
  2. SHA1’s internal state is 160 bytes in length whereas, HMAC SHA 1-96 has an internal state size of 196.
  3. In comparison, Cisco HMAC SHA 1 is less secure whereas HMAC SHA 1 96 provides a higher level of security than SHA1.
  4. Cisco HMAC SHA1 generates an output of 160 bits whereas, SHA 1 96 generates an output of 196 bits.
  5. SSL certificate authority use Cisco HMAC SHA 1 to sign certificates whereas, HMAC SHA 1 96 is a hash function that is often used in blockchain technology.

Conclusion

The two most popular secure hashing algorithms may now be compared to see which one is the best fit for your purposes. It is unrealistic to expect that a hashing algorithm will be secure for the next ten years. However, there is no need to be concerned, since the cryptography industry is always working to improve security. In the event that the old protocol fails, developers are always prepared with a new, more sophisticated, and secure protocol. When it comes to data security, hashing is by far the simplest and most effective method. A hashing algorithm has been known for a long time, and it has been shown to be vital for digital signatures as well.

If you’re still using SHA-1, visitors visiting your website will be alerted by browsers like Google Chrome that their data may have been compromised or handed to the incorrect person. Chrome’s security settings will be updated later this year, which means these alerts will become progressively more serious. If you don’t keep your SHA version up to date, you’re putting your site’s security at risk and may lose customers because of the increased security procedures in Chrome and other browsers.
