Decryption Errors: "Invalid Packet (ctb=15)" and "zlib inflate problem: invalid stored block lengths"

  • 1.  Decryption Errors: "Invalid Packet (ctb=15)" and "zlib inflate problem: invalid stored block lengths"

    We encrypted several zipped SAS datasets with PGP, but are receiving errors when we try to decrypt them (see below).  The files are over 2GB in size.    We know the files were not corrupt to begin with as we could load/view them in SAS.  Did the encryption process corrupt the files? Is there a way to decrypt these or recover the original contents?  Thanks in advance for your help.

    Hi blashmet,

    Was the archive moved to a different system or partition?

    That warning states that the message was manipulated, and that's likely to be the reason why you cannot decrypt it. Have you checked the hash (MD5/SHA) before and afer moving the file (or when it was generated and now)?
