There are several ways to condense the output of a cipher:

1. Compression: Use a compression algorithm to compress the cipher output. This will reduce the size of the output and make it easier to transmit or store.

2. Truncation: Truncate the output to a certain length. This may decrease the security of the cipher but will reduce the size of the output.

3. Hashing: Transform the output into a fixed-length hash value using a hash function. This will reduce the size of the output but may make it impossible to recover the original message.

4. Encoding: Use an encoding scheme to represent the output in a more compact form. Examples of encoding schemes include base64 and hexadecimal encoding.

5. Symmetric encryption: Use a symmetric encryption algorithm to encrypt the output. This will result in a smaller ciphertext than the original plaintext.
