-t, --textmode
--no-textmode
Treat input files as text and store them in the OpenPGP canonical text form with standard "CRLF" line endings. This also sets the necessary flags to inform the recipient that the encrypted or signed data is text and may need its line endings converted back to whatever the local system uses. This option is useful when communicating between two platforms that have different line ending conventions (UNIX-like to Mac, Mac to Windows, etc). --no-textmode disables this option, and is the default.
--force-v3-sigs
--no-force-v3-sigs
--force-v4-certs
--no-force-v4-certs
These options are obsolete and have no effect since GnuPG 2.1.
--force-mdc
--disable-mdc
These options are obsolete and have no effect since GnuPG 2.2.8. The MDC is always used. But note: If the creation of a legacy non-MDC message is exceptionally required, the option --rfc2440 allows for this.
--disable-signer-uid
By default the user ID of the signing key is embedded in the data signature. As of now this is only done if the signing key has been specified with local-user using a mail address. This information can be helpful for verifier to locate the key; see option --auto-key-retrieve.
--personal-cipher-preferences string
Set the list of personal cipher preferences to string. Use
gpg --version
to get a list of available algorithms,
and use none
to set no preference at all. 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. The most highly ranked cipher in this list is also
used for the --symmetric encryption command.
--personal-digest-preferences string
Set the list of personal digest preferences to string. Use
gpg --version
to get a list of available algorithms,
and use none
to set no preference at all. 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. The most highly ranked digest algorithm in this list
is also used when signing without encryption
(e.g. --clear-sign or --sign).
--personal-compress-preferences string
Set the list of personal compression preferences to string.
Use gpg --version
to get a list of available
algorithms, and use none
to set no preference at all. 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. The most highly ranked compression
algorithm in this list is also used when there are no recipient keys
to consider (e.g. --symmetric).
--s2k-cipher-algo name
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-digest-algo name
Use name as the digest algorithm used to mangle the passphrases for symmetric encryption. The default is SHA-1.
--s2k-mode n
Selects how passphrases for symmetric encryption are mangled. If n is 0 a plain passphrase (which is in general not recommended) will be used, a 1 adds a salt (which should not be used) to the passphrase and a 3 (the default) iterates the whole process a number of times (see --s2k-count).
--s2k-count n
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.
