*** PHP Version : 8.1.29 - Dolibarr Version : 18.0.0
*** print_r() of object used to generate the key to hash for blockedlog on the object sample:
stdClass Object
(
    [aaa] => aaa
    [bbb] => bbb
    [thirdparty] => stdClass Object
        (
            [ref_ext] => 
            [country_code] => 
            [state_code] => 
            [name] => MyBigCompany
            [name_alias] => 
            [address] => 
            [zip] => 
            [town] => 
        )

)
*** We build hash(256) of this string:
076c1e09ded059c856f81b750610dfc6a4093cd939fb89699c9e5ea7d5d67b48
*** When it is serialized() to store in db, we got:
O:8:"stdClass":3:{s:3:"aaa";s:3:"aaa";s:3:"bbb";s:3:"bbb";s:10:"thirdparty";O:8:"stdClass":8:{s:7:"ref_ext";N;s:12:"country_code";N;s:10:"state_code";N;s:4:"name";s:12:"MyBigCompany";s:10:"name_alias";N;s:7:"address";N;s:3:"zip";N;s:4:"town";N;}}
*** And when it is print_r(unserialized()) to reuse it:
stdClass Object
(
    [aaa] => aaa
    [bbb] => bbb
    [thirdparty] => stdClass Object
        (
            [ref_ext] => 
            [country_code] => 
            [state_code] => 
            [name] => MyBigCompany
            [name_alias] => 
            [address] => 
            [zip] => 
            [town] => 
        )
