Customize encryptor/decryptor

By default git-remote-crypt uses aes to encrypt/decrypt data:

_default_encryptor() {
	openssl enc -aes-256-cbc -pass pass:$GIT_CRYPT_KEY
}

_default_decryptor() {
	openssl enc -aes-256-cbc -d -pass pass:$GIT_CRYPT_KEY
}

You can choose another, like:

  cat << EOF > ~/my-git-crypt-encryptor
#!/bin/bash
openssl enc -des-cfb -pass pass:mysecret
EOF
  chmod +x ~/my-git-crypt-encryptor

  cat << EOF > ~/my-git-crypt-decryptor
#!/bin/bash
openssl enc -des-cfb -d -pass pass:mysecret
EOF
  chmod +x ~/my-git-crypt-decryptor

  export GIT_CRYPT_ENCRYPTOR=~/my-git-crypt-encryptor
