From Aegis to pass

Aegis is a nice android app to manage OTP tokens. pass is the password manager for *nix systems. I know that the whole point of the two factor authentication philosophy is to physically separate the bearers of authentication information, but the lifetime of my physical devices is quite random, so WHATEVER: I concoted this procedure to copy the OTP passwords from aegis to pass.

First: extract the PLAINTEXT secrets from aegis

In aegis, click on the three dots in the upper right angle, then go to Settings. Scroll to the end and select Export. Uncheck Keep the vault encrypted: we need the plain json. Choose a location where to save the file.

Share the file to your computer

THE SECRETS ARE IN PLAIN TEXT DO NOT PASS OVER INSECURE CHANNELS

I suggest to use adb pull.

Second: import the secrets in pass

You'll need pass and the pass-otp extension. Then use this script

#!/usr/bin/env bash

# The form of the url is the following:
# otpauth://totp/${email}?secret=${secret}&issuer=${issuer}

if [ ! -f "${1}" ]; then
    echo "Provide an input file"
    exit -1
fi

for _otpauth in $(cat ${1} |jq '.db.entries[] | "otpauth://" + .type + "/" + .name + "?secret=" + .info.secret + "&issuer=" + .issuer'); do
    otpauth=${_otpauth//\"}
    path=otp/$(echo ${otpauth} | sed -e 's|otpauth://[a-z]\+/\(.*\)?secret=.*&issuer=\(.*\)|\2/\1|')
    pass otp insert ${path} < <(echo ${otpauth})
done

It needs the json with the secrets whe discussed above. It organizes the secrets in the following fashon:

otp/<issuer>/<email>

Namely, a secret OTP from Google to [email protected] will have the form

otp/Google/[email protected]

To get the otp, just

pass otp otp/Google/[email protected]
