oracle中md5加密解密_Oracle定义DES加密解密及MD5加密函数示例

(1)DES加密函数create or replace function

encrypt_des(p_text varchar2, p_key varchar2) return varchar2 is

v_text varchar2(4000);

v_enc varchar2(4000);

raw_input RAW(128) ;

key_input RAW(128) ;

decrypted_raw RAW(2048);

begin

v_text := rpad( p_text, (trunc(length(p_text)/8)+1)*8, chr(0));

raw_input := UTL_RAW.CAST_TO_RAW(v_text);

key_input := UTL_RAW.CAST_TO_RAW(p_key);

dbms_obfuscation_toolkit.DESEncrypt(input => raw_input,key => key_input,encrypted_data =>decrypted_raw);

v_enc := rawtohex(decrypted_raw);

dbms_output.put_line(v_enc);

return v_enc;

end;

(2)DES解密函数create or replace function decrypt_des(p_text varchar2,p_key varchar2) return varchar2 is

v_text varchar2(2000);

begin

dbms_obfuscation_toolkit.DESDECRYPT(input_string => UTL_RAW.CAST
