Doc Text:	.Decrypting multipart uploads was corrupting data When doing multipart uploads with SSE-C, the part size was not a multiple of the 4k encryption block size. While the multipart uploads were encrypted correctly, the decryption process failed to account for the part boundaries and was returning corrupted data. With this release, the decryption process correctly handles the part boundaries when using SSE-C. As a result, all encrypted multipart uploads can be successfully decrypted.	Story Points:	---
