# GnuPG Options
# (OpenPGP-Configuration-Options)

# Assume that command line arguments are given as UTF8 strings.
utf8-strings


# ### (OpenPGP-Esoteric-Options)
# ============================================
#
# Use name as the message digest algorithm used when signing a key. Running the 
# program with the command --version yields a list of supported algorithms. Be 
# aware that if you choose an algorithm that GnuPG supports but other OpenPGP 
# implementations do not, then some users will not be able to use the key 
# signatures you make, or quite possibly your entire key.
# 
# SHA-1 is the only algorithm specified for OpenPGP V4. By changing the 
# cert-digest-algo, the OpenPGP V4 specification is not met but with even 
# GnuPG 1.4.10 (release 2009) supporting SHA-2 algorithm, this should be safe.
# Source: https://tools.ietf.org/html/rfc4880#section-12.2

# digest-algo SHA512 stronger

# Selects how passphrases for symmetric encryption are mangled. 3 (the default) 
# iterates the whole process a number of times (see --s2k-count).
s2k-mode 3


# ### (OpenPGP-Protocol-Options)
# ============================================
#
# Use name as the cipher algorithm for symmetric encryption with a passphrase 
# if --personal-cipher-preferences and --cipher-algo are not given. The 
# default is AES-128. 
s2k-cipher-algo AES256

# Use name as the digest algorithm used to mangle the passphrases for symmetric 
# encryption. The default is SHA-1. 
s2k-digest-algo SHA512

# Specify how many times the passphrases mangling for symmetric encryption is 
# repeated. This value may range between 1024 and 65011712 inclusive. The 
# default is inquired from gpg-agent. Note that not all values in the 
# 1024-65011712 range are legal and if an illegal value is selected, GnuPG will 
# round up to the nearest legal value. This option is only meaningful if 
# --s2k-mode is set to the default of 3. 
s2k-count 1015808
#s2k-count 65011712

# Set the list of personal digest/cipher/compression preferences. This allows 
# the user to safely override the algorithm chosen by the recipient key 
# preferences, as GPG will only select an algorithm that is usable by all 
# recipients.

# ### GnuPG View Options
# ============================================
#
# Select how to display key IDs. "long" is the more accurate (but less 
# convenient) 16-character key ID. Add an "0x" to include an "0x" at the 
# beginning of the key ID.
keyid-format 0xlong

# List all keys with their fingerprints. This is the same output as --list-keys 
# but with the additional output of a line with the fingerprint. If this 
# command is given twice, the fingerprints of all secondary keys are listed too.
