Use FunC Hash Functions

cell_hash

Calculates the representation hash of the given cell c and returns it as a 256-bit unsigned integer x. This function is handy for signing and verifying signatures of arbitrary entities structured as a tree of cells.

from tonutils.utils import cell_hash
from pytoniq_core import begin_cell


def main() -> None:
    c = begin_cell().store_string("ness").end_cell()
    x = cell_hash(c)
    print(x)


if __name__ == "__main__":
    main()

slice_hash

Computes the hash of the given slice s and returns it as a 256-bit unsigned integer x. The result is equivalent to creating a standard cell containing only the data and references from s and then computing its hash using cell_hash.

from tonutils.utils import slice_hash
from pytoniq_core import begin_cell


def main() -> None:
    s = begin_cell().store_string("ness")
    x = slice_hash(s)
    print(x)


if __name__ == "__main__":
    main()

string_hash

Calculates the SHA-256 hash of the data bits in the given slice s. A cell underflow exception is thrown if the bit length of s is not a multiple of eight. The hash is returned as a 256-bit unsigned integer x.

from tonutils.utils import string_hash


def main() -> None:
    s = "ness"
    x = string_hash(s)
    print(x)


if __name__ == "__main__":
    main()
