# crypt
crypt is a small app to encrypt and decrypt files with aes encryption. It is
portable and works on OSX, Linux, and Windows along with any other OS that
supports go.
A key can be specified with the `--key` flag or via stdin if `--key` is
not specified. You may want to provide your key via stdin for encryption
and decryption so that it is not saved in your bash history.
### Examples
**Encrypt the contents from STDIN to a file**
```bash
> echo "hello world" | crypt -e --key test -i encrypted-text
```
**Decrypt the contents from STDIN to STDOUT**
```bash
> cat encrypted-text | crypt -d --key test -i -o
hello world
```
**Encrypt a large tar file to a new file**
```bash
> crypt -e docker-image.tar encrypted-image.xxx
please enter your key:
> secret
1.24 GB / 1.25 GB [=========================================================================] 99.70 % 58.72 MB/s
# test to see if I can read the file
> tar -tvf encrypted-image.xxx
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
```
**Decrypt a large file back to the original contents**
```bash
> crypt -d encrypted-image.xxx docker-image-unencrypted.tar
please enter your key:
> secret
1.24 GB / 1.25 GB [=========================================================================] 99.45 % 70.80 MB/s
# look at the tar headers
> tar -tvf docker-image-unencrypted.tar
