Title: use sha256 instead of md5 in new formulas

"Do not use the MD5 algorithm
Software developers, Certification Authorities, website owners, and users should
avoid using the MD5 algorithm in any capacity. As previous research has
demonstrated, it should be considered cryptographically broken and unsuitable
for further use."
