Finally, it works :-) $crypt=$test->result(); echo "<br />"; echo "crypted content from postgresql: " .$crypt; echo "<br />"; $crypt=pg_unescape_bytea($crypt); echo $crypt; echo "<br />"; echo mcrypt_decrypt ( MCRYPT_RIJNDAEL_128 , "fooz", $crypt, cbc); echo "<br />"; echo mcrypt_cbc (MCRYPT_RIJNDAEL_128, "fooz", $crypt , MCRYPT_DECRYPT); OUTPUT: crypted content from postgresql: g°ñ\220399ùû¹qyg®Û~ g°ñ399ùû¹qyg®Û~ daniel daniel You have to use the function "pg_unescape_bytea();" from PHP when you extract bytea data from postgresql. How stupid of me, should have known that the bytea data would be escaped ;-) Daniel
