Your input data is corrupted. OpenPGP messages are constructed from
several packets, each packets starts with a tag byte commonly called CTB
indicating the type of the packet and how the length of the packet is
specified. 0x70 is not a valid CTB, thus you see this message.
A common cause for a corrupted message is the use of a non binary clean
channel (e.g. using ftp without switching to binary mode). Mail
software may also corrupt the message. Ask the sender of the message to
encapsulate it in a ZIP or tar file and than unzip it before decrypting.
If this works or you can't unzip it your transport channel is non 8 bit
clean. A quick work around would be the use of the --armor or -a
