How long is GPG passphrase?
A good passphrase should have at least 15, preferably 20 characters and be difficult to guess.
How long is a passphrase?
In general, passphrases should be as long as possible while still being easy-to-remember. Using a long, uncommon phrase of 32 characters or more that is memorable for you, personally, is a great way to do this — and it eliminates the need for most complexity requirements.
How long is a strong password?

When to use GnuPG’s passphrase FD argument?
As hypothesised the file descriptors get dumped after first usage by either GnuPG or a sub shell, thus the passphrase needs to be assigned before every decrypt command for bulk decryption to happen. Hope this was valuable to y’all. Thanks for contributing an answer to Stack Overflow!
What does GPG preset-passphrase do in GPG 8.6?
8.6 Put a passphrase into the cache. The gpg-preset-passphrase is a utility to seed the internal cache of a running gpg-agent with passphrases. It is mainly useful for unattended machines, where the usual pinentry tool may not be used and the passphrases for the to be used keys are given at machine startup.
When do passphrases in GPG do not expire?
Passphrases set with this utility don’t expire unless the –forget option is used to explicitly clear them from the cache — or gpg-agent is either restarted or reloaded (by sending a SIGHUP to it). Note that the maximum cache time as set with –max-cache-ttl is still honored.
What are the standard file descriptors in GnuPG?
The standard file descriptors are STDIN (0), STDOUT (1) and STDERR (2). For the context of this question, you would normally only be concerned about STDIN (0). You didn’t specify where you want the passphrase to come from, so I will demonstrate the usage of STDIN (standard in) in a variety of ways.
