Hi every body Is there any 1024 bits hash function can i use with harbour programs?

Hi

On this link

https://github.com/Petewg/harbour-core/wiki/hb_S 

You can find this text

• hb_SHA1(<cBuffer> [, <lBin>]) ➜ cDigest
• hb_SHA224(<cBuffer> [, <lBin>]) ➜ cDigest
• hb_SHA256(<cBuffer> [, <lBin>]) ➜ cDigest
• hb_SHA384(<cBuffer> [, <lBin>]) ➜ cDigest
• hb_SHA512(<cBuffer> [, <lBin>]) ➜ cDigest
  Above functions are used to calculate hash value (digest) of given <cBuffer> according to SHA-1, SHA-2, SHA-3 Secure Hash Algorithms.
  <lBin> flag controls whether to return binary data or hexadecimal string, default .F., that is, return hexadecimal string.

 Regards,

Simo.

Hi thank you my dear brother for your precious answer ..but what i am looking for is 1024 bits hash function all  those functions you give me is generated hash below 1024 bits ..so is there any other hash function can generate 1024 bits hash?

Hello

Generating a 1024-bit hash for encryption is not considered necessary, for personal use 512 is more than enough, which is why it has not been implemented.

For more secure communication, it is not recommended either, for example Microsoft is going to discontinue its use, it recommends the use of a 2048-bit hash.

Thank you very much my dear brother for your precious information ,from what you give me regarding SHA-3 as it is mentioned in wiki there is SHAKE 256 how i can use this hash function(SHAKE256) in Harbour where i can get its code and how i can include it in my Harbour program?    

[veparakos esperantoshio]

Hi my all dear brothers...i am still waiting for your answer about my question ... how i can use hash function(SHAKE256) in Harbour ,where i can get its code and how i can include it in my Harbour program?    

[juanpere...@gmail.com]

Hello

An example of how to use SHAKE256 in harbour and it is in the hbcrypto.lib library

C:\MiniGUI\Harbour\lib

Source code

C:\MiniGUI\SOURCE\HbCrypto

procedure main()

    ? "sha3 256"
    ? hb_sha3256("i can include it in my Harbour program")
    ? hb_sha3256("whereicangetitscode")
    ? "--------------------------"
    ? "sha3 512"
    ? hb_sha3512("i can include it in my Harbour program")
    ? hb_sha3512("whereicangetitscode")
    ? "--------------------------"
    ? "SHAKE256"
    ? hb_shake256("i can include it in my Harbour program")
    ? hb_shake256("whereicangetitscode")

return

Thank you very much for your precious answer ...can you give me direct link to download the  hbcrypto.lib in one file only  so i can include it in my program.

Hello

Thank you my brother for your precious answer but google drive ask me to wait for permission to access the file...can you upload the same file other than google drive.

Thank you very much for your precious answer my dear brother ...but how i can include the file in my program ?!  

[juanpere...@gmail.com]

Hi 

It depends on how you compile in harbour on the command line or with some application. 

With hbmk2 with the -l option, non-standard libraries are included.

You can also use QPM https://teamqpm.github.io/

Thank you very much my brother for your precious answer ...i tried what you said but i am getting this error:
 Error F0029  Can't open #include file 'C:\PWCT19\ssbuild\minigui\Harbour\lib\hbcrypto.lib'

i am still waiting for your precious answers my dear brothers

What minigui do you use, what c compiler?
I use https://www.hmgextended.com/ ,  Borland C++ compiler Version 5.8 and it works without error.
