You can encode integer into hexadecimal string: >>> int_to_enc(20190925, enc_table_16) '13416cd' To verify use, python's hex() function: >>> hex(20190925) '0x13416cd' You can encode integer using 64 digit table: >>> int_to_enc(20190925, enc_table_64) '1d1rd' rÚNéÿÿÿÿ)ÚlenÚint)ÚnÚ enc_tableÚbaseÚdigits©r ú./util/cmf_hashlib.pyÚ int_to_encs r écCsH|dkrtd |¡ƒ‚t | ¡¡}| ¡}tt|dƒ|ƒ}|d|…S)a”Geneate string hash with given length, using specified encoding table.
