### Upload encrypted password protected files
By default files upload for only 1 download, you can specify download limit using -D flag like `transfer-encrypted -D 50 %file/folder%`
#### One line for bashrc
```bash
transfer-encrypted() { if [ $# -eq 0 ]; then echo "No arguments specified.\nUsage:\n transfer <file|directory>\n ... | transfer <file_name>" >&2; return 1; fi; while getopts ":D:" opt; do case $opt in D) max_downloads=$OPTARG;; \?) echo "Invalid option: -$OPTARG" >&2;; esac; done; shift "$((OPTIND - 1))"; file="$1"; file_name=$(basename "$file"); if [ ! -e "$file" ]; then echo "$file: No such file or directory" >&2; return 1; fi; if [ -d "$file" ]; then file_name="$file_name.zip"; (cd "$file" && zip -r -q - .) | openssl aes-256-cbc -pbkdf2 -e > "tmp-$file_name" && cat "tmp-$file_name" | curl -H "Max-Downloads: $max_downloads" -w '\n' --upload-file "tmp-$file_name" "https://transfer.sh/$file_name" | tee /dev/null; rm "tmp-$file_name"; else cat "$file" | openssl aes-256-cbc -pbkdf2 -e > "tmp-$file" && cat "tmp-$file" | curl -H "Max-Downloads: $max_downloads" -w '\n' --upload-file - "https://transfer.sh/$file_name" | tee /dev/null; rm "tmp-$file"; fi; }
```
#### Human readable code
```bash
transfer-encrypted() {
if [ $# -eq 0 ]; then
echo "No arguments specified.\nUsage:\n transfer <file|directory>\n ... | transfer <file_name>" >&2
return 1
fi
while getopts ":D:" opt; do
case $opt in
D)
max_downloads=$OPTARG
;;
\?)
echo "Invalid option: -$OPTARG" >&2
;;
esac
done
shift "$((OPTIND - 1))"
file="$1"
file_name=$(basename "$file")
if [ ! -e "$file" ]; then
echo "$file: No such file or directory" >&2
return 1
fi
if [ -d "$file" ]; then
file_name="$file_name.zip"
(cd "$file" && zip -r -q - .) | openssl aes-256-cbc -pbkdf2 -e > "tmp-$file_name" && cat "tmp-$file_name" | curl -H "Max-Downloads: $max_downloads" -w '\n' --upload-file "tmp-$file_name" "https://transfer.sh/$file_name" | tee /dev/null
rm "tmp-$file_name"
else
cat "$file" | openssl aes-256-cbc -pbkdf2 -e > "tmp-$file" && cat "tmp-$file" | curl -H "Max-Downloads: $max_downloads" -w '\n' --upload-file - "https://transfer.sh/$file_name" | tee /dev/null
rm "tmp-$file"
fi
}
```
#### Decrypt using
```bash
curl -s https://transfer.sh/some/file | openssl aes-256-cbc -pbkdf2 -d > output_filename
```
## Uploading and copy download command
Download commands can be automatically copied to the clipboard after files are uploaded using transfer.sh.
