It is currently support following hash algorithms:

  • MD2
  • MD4
  • MD5
  • SHA1
  • SHA224
  • SHA256
  • SHA384
  • SHA512
  • HMAC-MD5
  • HMAC-SHA1
  • HMAC-SHA224
  • HMAC-SHA256
  • HMAC-SHA384
  • HMAC-SHA512
  • Base64 encode/decode for text

Beside that, this app can calculate hash for text contents; this app can also check whether two files are identical or not. This app is great for check file integrity that downloaded from the internet.
