(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_TO_varchar2(p_text),key_string =>p_key, decrypted_string=> v_text);
- v_text := rtrim(v_text,chr(0));
- dbms_output.put_line(v_text);
- return v_text;
- end;
(3)MD5加密函数
- CREATE OR REPLACE FUNCTION MD5(passwd IN VARCHAR2)
- RETURN VARCHAR2
- IS
- retval varchar2(32);
- BEGIN
- retval := utl_raw.cast_to_raw(DBMS_OBFUSCATION_TOOLKIT.MD5(INPUT_STRING => passwd)) ;
- RETURN retval;
- END;
(4)函数使用示例
DES加密: update tb_salarysign_staff s set s.staffpwd =encrypt_des(s.staffpwd, 'test#5&124*!de');
DES解密:select decrypt_des(s.staffpwd, 'test#5&124*!de') from tb_salarysign_staff s
MD5加密: update tb_salarysign_staff s set s.staffpwd = md5(s.staffpwd);
