| description: | |
| The AWS S3 Crypto SDK sends an unencrypted hash of the plaintext alongside |
| the ciphertext as a metadata field. This hash can be used to brute force |
| the plaintext, if the hash is readable to the attacker. |
| |
| AWS now blocks this metadata field, but older SDK versions still send it. |
