It looks like SHA1 is the default hashing algorithm for `tpm2_hash`. Could we change this to SHA256 or anything that is not deprecated? ``` root@9ac55cfa586b:~/lab/chapter_D# tpm2_hash -o hash.txt --hex random.bin root@9ac55cfa586b:~/lab/chapter_D# cat hash.txt 0d0cda9c13ececee74e8c61bf363233a906f6b84 root@9ac55cfa586b:~/lab/chapter_D# sha1sum random.bin 0d0cda9c13ececee74e8c61bf363233a906f6b84 random.bin ``` where random.bin is just 64 bytes of random data as produced by tpm2_getrandom.
