However, that is not all you can do on Online-Convert.com! As an additional feature you can create checksums and hashes using different algorithms.

Since we get quite some questions about our hash creation, we decided to create this frequently asked questions (FAQ) entry for you.

 

Hash Generation FAQs

 

What Is The Difference: Encoding, Encryption & Hashing

In the past we have written a long and informative article about the difference between these three. You can re-read it here or check out the small summary below:

Encoding, Encryption, and Hashing

Encoding Encryption Hashing
Data Security Not secure Secure Secure
Reversibility Reversible Reversible Not Reversible

Looking at the table above, the difference between the three systems becomes very apparent.

  • Encoding should not be used to secure data since the data is easily decoded. As soon as the encoding system is known, the data can be decoded using the very same system.
  • Encryption, however, can be used for securing data since it can only be de-crypted with a respective key, even when the encryption method is known.
  • Hashing is also a safe method to secure data. However, once hashed the data can not be reversed to its original form again.

 

What Do I Need A Hash Generator For?

Hashes and checksums are used to create a string of characters out of different data entries. This way, sensitive data can be secured. Furthermore, hashes change their form once the input is altered. These two basic functions can be used for several purposes like:

  • Searching in a big database
  • Checking downloads & sent/transmitted data
  • Comparing passwords without saving the actual password
  • Detecting duplicate content or alterations in general

Detailed descriptions of the usages mentioned above can be found here:

What Algorithm Should I Choose?

Online-Convert.com provides a big list of different hashing algorithms and encryption ciphers you can choose from. Of course it is not an exhaustive list, but it provides a good selection of different systems.

Since listing the pros and cons as well as the advantages of each algorithm or cipher would exceed the span of this article, have a look at this separate article about the advantages and functions of different hash generators:

Different Hash Functions and their Advantages

 

How Do I Create A Hash/Checksum?

Once you decided on your method, you can start creating checksums from your data. With Online-Convert.com, this is fairly easy.

OC_Hashing

There are four main methods of providing data you want to have hashed or encrypted:

  1. Paste text you wish to convert into a hash or checksum
  2. Upload a file
  3. Enter the URL to a file or website you want to generate a hash from
  4. Choose a file from a cloud service like Dropbox and Google Drive

Afterwards, click on convert file and wait a little until the checksum is created.

What Else Is There To Know?

As you have probably seen above, there are also optional settings available for the hash generation. Lets have a look at them.

 

HMAC Hashes:

Some hashes have been generated using a keyed-hash message authentication code (HMAC). In order to provide a correct hash for comparison, the HMAC of the original hashing should be entered.

This is available for the following methods:

Adler32, CRC, Gost, Haval, MD4, MD5, RIPEMD, SHA, Snefru, Tiger, Whirlpool

 

Salt:

A salt can be used for hash generation to extra-secure the hashes. When added, the salt provides additional security against dictionary and rainbow table attacks.

This is available for:

Blowfish, htpasswd Apache

 

Rounds:

Some hash functions are able to generate hashes using different rounds. The hashes differ depending on the number of rounds used for the generation. The default value, using Online-Convert.com is 3 rounds, but you can choose 4 or sometimes even 5 rounds as well.

This is available for:

Haval, Tiger

For those looking for an easy to use hash generator Online, then Online Convert offers you one with many different formats to convert to. Hash encryption used to be something that most of us heard on TV or movies involving high-tech plots. However, with the recent upsurge in Internet and electronic device usage these days, that is no longer the case. Hash encryption is everywhere and if you are not using it to protect your sensitive data, you could be in danger of hackers or scams.

 

 

 

 

Hash Encryption Defined

 

Hash encryption are cryptographic hash functions which are considered almost impossible to invert or devalue. One simple way to look at a hash function is by thinking of it this way; if you take the number 5 (five) and send it to someone, then it is easy to see it just as it is; the number 5. However, if you add hash encryption to the same number 5, it might turn out to be something like this – 8AEGHDC7 F67HGH7CA 98K24LM 45JH87KC KD392OP – which is nearly impossible to decode or figure out.  Another way to look at hash encryption is by thinking of baking a loaf of bread. With a loaf of bread, you first start out with your inputs ie; flour, yeast, water, etc. When you apply the hash function (baking + mixing) then you end up getting the end results which is a loaf of baked bread. There are many different hash functions such as binary or string. A hash function is considered any function which can be utilized to map data of arbitrary proportions to data of fixed size.

Why The Need For Hash Encryption?

 

As we stated earlier, the rise in both Internet usage and people with access to Online sites has risen quite dramatically the past few years. Electronic devices have made this possible since people no longer need just a computer or laptop to go online anymore. Because of this rise in Online usage, there is also a spike in hacking and cyber crimes. This means that having simple and/or easy to remember passwords is dangerous and not recommended. Hash encryption allows you to create hashes for important & sensitive data such as passwords. Having well encrypted passwords can help protect your personal data, files and financial information as well.

 

Still, there are many Websites which charge users for hash encryption. Other sites offer to do so but only if you sign up or download certain programs or software. None of these options are needed for hash encryption if you use Online Convert’s hash encryption tools. And yes, they are not just easy to use, but also totally free. For others looking to calculate the checksum of their files, you can also do that here as well.

What’s Your Hash Function?

 

If you are looking for ways to hash encrypt or convert files into MD4, Adler32, SHA-1 or any other formats, simply go to Hash Generetion and choose the generator required. From here you can generate a hash using Haval 128 Bit encryption tool or calculate your GOST hash from your passwords. There are all kinds of options to choose from which is pretty awesome and helpful.

Remember, always keep your personal information such as passwords stored in at least two different safe places in case you lose access to one. Of course, access to these places should be encrypted and well protected. There are Apps such as LastPass which work great in storing and keeping all of your passwords in one place.  Being able to browse or do whatever you choose to do Online should be safe and easy. By using Hash encryption and protecting yourself and your data, you are making sure that is always the case.

Hashing and Encrypting – What’s the Difference?

Many people often get confused when it comes to knowing the differences between hashing and encrypting. Online-convert.com has put together this article to help better explain about hashing and encrypting and what’s the difference between both of these important security tools.

 

What is Encryption?

With so many hackers on the Internet today, without encryption, the web would be like finding a bank vault full of cash wide open with no police around. Think of encryption as thousands of hard to open locks systematically placed to stop intruders. Encryption actually turns data into an array of indecipherable characters. These unreadable characters are not  created into a fixed length so therefore they are almost impossible to decipher or decode.

 

One huge difference that hashing and encryption have from each other is that if you have the right key or code, you can actually reverse back encrypted strings to their original  form. Public key encryption and Symmetric key encryption are two primary types of encryptions.

 

While public key encryption has two different keys, in symmetric key encryption both keys are the same. In the public key encryption, one is used to first encrypt the string of data while the private key is then used to decrypt it. Only the person receiving the encrypted messages has access to the private key which allows them to decode the messages even though the public key is accessible for anybody to use it to encrypt their messages. Two popular algorithms are PGP (Public key encryption algorithm) and AES which uses 256 bits of key size so it is considered the gold standard encryption key.

What is Hashing?

While a hash is a number or a string developed from a string of text,  unlike encryption, the number or string reproduced by hashing results in a fixed length number. The generated string or number will greatly differ with minuscule variations in input.

It is impossible to turn a hash back into its original number or string since the hashing algorithms are constructed for just that. Two popular algorithms are MD5 which produces a 16 byte hash value and SHA which produces a 20-byte hash value.

 

If wasn’t for both hashing and encrypting, the billions of amounts of data which flows through the Internet daily would be in jeopardy. All of our personal information, credit cards and banking, would be wide open for hackers or anyone to access and use. So we need hashing and encrypting to make our world a safer place; especially in a world where just about everything flows through the web everyday.
