The size limit is 4KB. If you want to digitally sign data larger than 4KB, you have the option to create a message digest of the data and send it to AWS KMS. The digital signature is created over the digest of the data and returned. You specify whether you are sending the full message or a message digest as a parameter in the Sign API request. Any data submitted to the Encrypt, Decrypt, or Re-Encrypt APIs that require use of asymmetric operations must also be less than 4KB.
