You can't change those bytes becuase they are signed and GnuPG check the signature of course. The far easiest way to change the preferences is by editing g10/keygen.c, function keygen_add_std_prefs() where you find this: buf[0] = CIPHER_ALGO_RIJNDAEL; buf[1] = CIPHER_ALGO_TWOFISH; buf[2] = CIPHER_ALGO_CAST5; buf[3] = CIPHER_ALGO_BLOWFISH; build_sig_subpkt( sig, SIGSUBPKT_PREF_SYM, buf, 4 ); Easy to change. The go to the edit menu and change the expireation time for the main key ("expire"). This create the new preferences. You may want to change the expiration time back to the old value immediatley after that.
