ChatGPT says, the 'ice.privatekey_to_address' function requires the private key to be a 32-byte integer. is it right or not? can you explain?

Hello.
p = ice.scalar_multiplication(1000)
ice.point_sequential_decrement(5, p).hex()

when I subtract 5 from the public key, I expect it to be P - 5, but not like 5 keys merged into one line:

Let's say I have a key
p2 = ice.scalar_multiplication(181786578786240192808009809421)
I need to subtract another 19184787898211 from p2 key and find out what public key it will be, how can I do this?

• in a for 10000 times use ice.point_negation(p2)
  or
• point_sequential_decrement(19184787898211 , p) but here I will get not 1 key, but many 19184787898211

please add privatekey to pubkey function....

pubkey_to_ETH_address_bytes

can you add node.js support?

Hi

a1 = ice.get_sha256('test')
print(a1)

a2 = ice.get_sha256('test2')
print(a2)
print(a1)

return

b'\x9f\x86\xd0\x81\x88L}e\x9a/\xea\xa0\xc5Z\xd0\x15\xa3\xbfO\x1b+\x0b\x82,\xd1]l\x15\xb0\xf0\n\x08'

How to fix this without unnecessary action

a1 = bytearray.fromhex(ice.get_sha256('test').hex())

I need a return in bytes

pls add function privkey to public key

I get about 400/second with point_multiplication, while scalar_multiplication is about 23K/second.
Please advice

EDIT: fixed typo

Hello! Can u add support for TRX please!

I did not find how to get the public key from the private key. Is this possible with this code?

This problem occurs since windows 10 update to version 21H2... the dll file is not found even though it is present in the folder..

Good afternoon, please add to the DLL possibly recalculating SHA256 as many times as needed.
e.g. get_sha256(input_bytes, iteration)
get_sha256(b'a', 2048)

Hi there:
Quick question.
I am using this library with pypy3 and seems to work fine with compress and uncompress btc address.
But when try something like that:
mykey = int(key,16)
hash160 = ice.privatekey_to_h160(0, True, mykey).hex()
print(hash160)
I just got only 40 zeros = 0000000000000000000000000000000000000000
Can you spot a solution, thanks!

aka long bech32 addresses.

thank you.

why didn't you add it?

def upub2cpub(upub_bytes):
x1 = upub_bytes[1:33]
prefix = str(2 + int(upub_bytes[33:].hex(), 16)%2).zfill(2)
return bytes.fromhex(prefix)+x1

Please add in the next version. This is what I needed.

Please delete it

if you share source code we could learn about itegration py with c

P4 = ice.point_sequential_increment(500000, P)
P4[:65].hex()

above example print one line 65byte
without this print is like first 10 pubkeys like this

how to get line by line print of selected 10, P or 500000, P ???

also mention line by line cpub print please...

Hi there,

I get a segmentation fault when running the script:

any idea how to fix it?

Thanks.

How to run on GPU ?

Hello! Please, add support for MacOS system.

Hello, little problem.
`
P='02504673bb8f9a16e40227b4ee12fb8d940630cb687fbc98c1747493d18e22f39c'

P = ice.pub2upub('02504673bb8f9a16e40227b4ee12fb8d940630cb687fbc98c1747493d18e22f39c')
xx=ice._point_sequential_decrement(15, P)
for t in range(10):
OnePub = xx[t65:t65+65]
print(ice.point_to_cpub(OnePub));
_bits, _hashes, _bf =ice.Fill_in_bloom(xx, _fp = 0.000001)
ice.dump_bloom_file('my_bloom_file3.bin',_bits, _hashes, _bf)
xsxa='023df3506a9994ad4a28bf59a14fecd436a2871d257129d6b3bbd02a9d5cafaef5'
xsxa = ice.pub2upub(xsxa)
print(ice.check_in_bloom(xsxa, _bits, _hashes, _bf))`

the xsxa public key in byte representation is exactly contained in the array passed to the "Fill_in_bloom" function
However, checking for presence in bloom - returns False

PS public keys obtained using the "point_subtraction" function and added to bloom are checked and found.
"check_in_bloom" function returns true

The function ice.scalar_multiplications([43242, 543053, 329074523, 321785444032743]) (taken from examples) provides only the result for the last value in the set.

HI

can you share the project files for ice_secp256k1.dll?

thank you for all your work

when i run my script, its outputed on my vps

Hello,
Any source code for the library, so we can compile it in Mac? and use it in our C applications.

Thanks!

this works great. Thanks.
How can I use 2 blooms in one program?

You did a great job, your library is magically fast. You have a lot of interesting works in the repository.
But there is one point that confuses, site virustotal claims that there is a signature for a possible attack inside the DLL.
Could you post the source code of the DLL or fix the potential threat?
Below is the text from virustotal sites:
