Default SRA decryption help

Dear all,

I have a couple of *.sra.ncbi_enc files and I am trying to decrypt them; however, NCBI website is very confusing:

1. Here they say that:

The password is not given on the command line. It must be in a a file that should be able to be read only by the user account running the program.

The location of that file should be found in one of these places in order:

1. An environment variable VDB_PWFILE

2. The VDB Configuration file option 'krypto/pwfile'
2. Here they say:

Decryption password and dbGaP repository key.

Recently implemented “dbGaP repository key” is a dbGaP project wide security token required for running NCBI SRA toolkit and decryption tools. The key is provided in a file with suffix “.NGC”. Currently it needs to be downloaded from “My Research Projects” page of PI’s dbGaP account.

3. Another Seqnaswers fellow told me to do this which did not work as well:

1. make a new folder at your home directory: /home/xxx/.ncbi
2. create a file named vdb-passwd and save your passwd in it
3. run vdb-decrypt
Any ideas?
