Ubuntu Manpage: sq encrypt - Encrypt a message

NAME

       sq encrypt - Encrypt a message

SYNOPSIS

       sq encrypt [OPTIONS] FILE

DESCRIPTION

       Encrypt a message.

       Encrypt  a  message for any number of recipients and with any number of passwords, optionally signing the
       message in the process.

       The converse operation is `sq decrypt`.

       `sq encrypt` respects the reference time set by the top-level `--time` argument.  It uses  the  reference
       time when selecting encryption keys, and it sets the signature's creation time to the reference time.

OPTIONS

Subcommand options
-B, --binary
Emit binary data

--compression=KIND
Select compression scheme to use

--encrypt-for=PURPOSE
Select what kind of keys are considered for encryption. 'transport' selects subkeys marked as
suitable for transport encryption, 'storage' selects those for encrypting data at rest, and
'universal' selects all encryption-capable subkeys.

-o, --output=FILE
Write to FILE or stdout if omitted

--private-key-store=KEY_STORE
Provide parameters for private key store

--recipient-cert=FINGERPRINT|KEYID
Encrypt to the named certificates

--recipient-email=EMAIL
Encrypt to all certificates that can be authenticated for the specified email address

--recipient-file=CERT_RING_FILE
Encrypt to all certificates in CERT_RING_FILE

--recipient-userid=USERID
Encrypt to all certificates that can be authenticated for the specified User ID

-s, --symmetric
Prompt to add a password to encrypt with. When using this option, the user is asked to provide a
password, which is used to encrypt the message. This option can be provided more than once to
provide more than one password. The encrypted data can afterwards be decrypted with either one of
the recipient's keys, or one of the provided passwords.

--set-metadata-filename
Set the filename of the encrypted file as metadata. Do note, that this metadata is not signed and
as such relying on it - on sender or receiver side - is generally considered dangerous.

--set-metadata-time=TIME
Set time for encrypted file as metadata. Allows setting TIME either as ISO 8601 formatted string
or by providing custom keywords. With `none`, the metadata is not set. With `file-creation`, the
metadata is set to the file's creation timestamp. With `file-modification`, the metadata is set
to the file's last modification timestamp. With `message-creation`, the metadata is set to the
creation timestamp of the message for which the metadata is added. Do note, that this metadata is
not signed and as such relying on it - on sender or receiver side - is generally considered
dangerous.

--signer-file=KEY_FILE
Sign the message using the key in KEY_FILE

--signer-key=KEYID|FINGERPRINT
Sign the message using the specified key on the key store

--use-expired-subkey
If a certificate has only expired encryption-capable subkeys, fall back to using the one that
expired last

FILE Read from FILE or stdin if omitted

Global options
See sq(1) for a description of the global options.

EXAMPLES

       Encrypt a file using a certificate

              sq encrypt --recipient-file romeo.pgp message.txt

       Encrypt a file creating a signature in the process

              sq encrypt --recipient-file romeo.pgp --signer-file juliet.pgp \
                     message.txt

       Encrypt a file using a password

              sq encrypt --symmetric message.txt
