# sq-autocrypt-encode-sender(1)

Encodes a certificate into an Autocrypt header

## NAME

encode-sender - Encodes a certificate into an Autocrypt header

## SYNOPSIS

**encode-sender** \[**-o**\|**--output**\] \[**--email**\] \[**--prefer-encrypt**\] \[**-h**\|**--help**\] \[*FILE*\]

## DESCRIPTION

Encodes a certificate into an Autocrypt header

A certificate can be encoded and included in a header of an email message.  This command encodes the certificate, adds the senders email address (which must match the one used in the "From" header), and the senders "prefer-encrypt" state (see the Autocrypt spec for more information).

The converse operation is "sq autocrypt decode".

## OPTIONS

- **-o**, **--output**=*FILE*

  Writes to FILE or stdout if omitted

- **--email**=*ADDRESS*

  Sets the address \[default: primary userid\]

- **--prefer-encrypt**=*PREFER-ENCRYPT* \[default: nopreference\] \[possible values: nopreference, mutual\]

  Sets the prefer-encrypt attribute

- **-h**, **--help**

  Print help information

- \[*FILE*\]

  Reads from FILE or stdin if omitted

## EXAMPLES

 Encodes a certificate

```
 sq autocrypt encode-sender juliet.pgp
```

 Encodes a certificate with an explicit sender address

```
 sq autocrypt encode-sender --email juliet@example.org juliet.pgp
```

 Encodes a certificate while indicating the willingness to encrypt

```
 sq autocrypt encode-sender --prefer-encrypt mutual juliet.pgp
```
