for sha1 what library will be better libgcrypt or openssl

[cieslarmichal]

Well we have some implementations in crypto module but its sha256, we can add sha1 there as well, copy paste from some online resources and add annotation about the source as we cannot use any external libs

[kumar80]

any specific reason why can't we use external libs?

[cieslarmichal]

Yup, people want to use libs with as little dependencies as possibile

[cieslarmichal]

Example when i was starting this project I had boost and people were saying cool lib but there is boost deps I wont use it 😁

for uuidV5 , what's "some data" in "SHA1 hash of some data" ? is it a random data ?
as per this it requires two inputs

uuidv5 function should take two input arguments, one data which user passes like some string and the second is a namespace which is a reference uuid user can also pass but it is optional and we can set it default to "bfd98c8e-48c0-46af-bf44-255d24883f8f"

[kumar80]

Implementation for UUID5 is done. can you please check if anything needs to be changed ?
