What is DisablePayloadSigning?
When you send data to Amazon S3, there's a process called "signing" that ensures the data you're sending is secure and hasn't been tampered with. This is like putting a unique seal on a letter before sending it.
The DisablePayloadSigning option lets you decide whether to use this "seal" for certain requests. By default, the seal is always applied. But in some cases, you might choose not to use it.
Why would you not use the seal?
Performance: Applying the seal takes some computing power. If you're sending a lot of data quickly, like uploading a big file to S3, not using the seal can speed things up a bit.
Other Safety Checks: Even without this specific seal, there are other ways to ensure data safety. For example, using a secure connection (HTTPS) and another method called MD5 hashing, you might feel safe enough without the extra seal.
Things to Remember:
This option mainly affects two specific actions: putting an object in S3 and uploading a part of a larger object.
If you turn off both the seal and MD5 hashing, the secure connection (HTTPS) becomes the primary way to ensure your data isn't corrupted during transfer.
In Simple Terms:
DisablePayloadSigning is like choosing not to put a special seal on a letter you're mailing. It can speed up the mailing process, but you should make sure the envelope is sturdy and the postman is trustworthy!
What is DisableMD5Stream?
DisableMD5Stream is an option when sending data to Amazon S3. Normally, data sent to S3 undergoes an MD5 check, which is like a digital fingerprint, ensuring the data hasn't been tampered with. This option lets you decide if you want to skip this check.
Why might you skip the MD5 check?
Skipping the MD5 check can speed up the data transfer process, especially when the computer is busy with other tasks. However, if you skip both this check and the signing "seal" (using DisablePayloadSigning), then a secure connection (HTTPS) becomes your main guard against data corruption.
In Simple Terms:
Think of DisableMD5Stream as choosing not to double-check a package's contents before sending. It can make the sending process faster, but you'll want other safety measures in place.
