-> decrypt it with your ssh private key using the following command:
+**bash script to encrypt data using a users ssh public key**

+If you received a message from someone that was encrypted with this script, you can decrypt it with your ssh private key using the following command without installing anything:
 ```
-./sshenc.sh -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt
+bash <(curl -s https://raw.githubusercontent.com/5im-0n/sshenc.sh/master/sshenc.sh) -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt
 ```
+sshenc.sh uses openssl under the hood, so you need to have that installed in your path to make it work.

-## install
+## Install
 ```
-wget wget https://sshenc.sh/sshenc.sh
+curl -O https://raw.githubusercontent.com/5im-0n/sshenc.sh/master/sshenc.sh
 chmod +x sshenc.sh
 ```

-## examples
+## Examples

 ### encrypt a file using your own ssh public key
 ```
-./sshenc.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt
+sshenc.sh -p ~/.ssh/id_rsa.pub < plain-text-file.txt > encrypted.txt
 ```

 ### encrypt a file using multiple recipients (broadcast encryption)
 ```
-./sshenc.sh -p ~/.ssh/id_rsa.pub -p id_rsa-alice.pub -p id_rsa-bob.pub < plain-text-file.txt > encrypted.txt
+sshenc.sh -p ~/.ssh/id_rsa.pub -p id_rsa-alice.pub -p id_rsa-bob.pub < plain-text-file.txt > encrypted.txt
 ```

 ### encrypt a file using the public key of a github user
 ```
-./sshenc.sh -p <(curl -sf "https://github.com/S2-.keys" | grep ssh-rsa | tail -n1) < plain-text-file.txt
+sshenc.sh -g S2- < plain-text-file.txt
 ```
-
-this line fetches the first public key for the github user `S2-` and encrypts the file `plain-text-file.txt` using this key.
+this line fetches the public keys for the github user S2- and encrypts the file plain-text-file.txt using its key(s).

 ### decrypt a file
 ```
-./sshenc.sh -s ~/.ssh/id_rsa < encrypted.txt
+sshenc.sh -s ~/.ssh/id_rsa < encrypted.txt
 ```
+
+## Notes
+[OpenSSL 1.1.1](https://www.openssl.org/docs/man1.1.1/man1/openssl-enc.html) introduced a not backwards compatible change: the default digest to create a key from the passphrase changed from md5 to sha-256.  
+Also, a new `-iter` parameter to explicitly specify a given number of iterations on the password in deriving the encryption key was added.  
+Before OpenSSL 1.1.1 this option was not available.  
+Since the new parameters are more secure, `sshenc.sh` changed to adopt them, so since 2019-11-26, files encrypted with a previous version of `sshenc.sh` will not decrypt.  
+To do so, use the prevous `sshenc.sh` script, located at [https://raw.githubusercontent.com/5im-0n/sshenc.sh/master/sshenc-pre1.1.1.sh](https://raw.githubusercontent.com/5im-0n/sshenc.sh/master/sshenc-pre1.1.1.sh).
