PDF Encryption: encrypted string with 0x0D gives error in Acrobat.

-

i generating enrypted pdf using standard password security handler cfm "aesv3" i.e 256-bit aes. issue if encrypted string  in pdf contains byte 0x0d i.e "cr", acrobat  9/x  not understand it. part/object of pdf such string associated  behaves erroneously.  if string not have 0x0d byte in , works fine. per pdf spec 1.7, string can have standalone cr byte.

any appreciated.

thanks.

we’d need see example pdf demonstrates problem.

 

but why putting cr password string, since difficult/impossible user enter characters on keyboard.
