Support for pre-hashing (HashEdDSA) was added.

The -H command-line switch, in addition to -S, enables HashEdDSA signatures instead of the default, pure EdDSA signatures.

HashEdDSA signatures:

  • Require very little memory to be generated and verified, even with huge files
  • Are faster to generate and verify than pure EdDSA signatures
  • Require Minisign >= 0.6. In particular, they are not compatible with OpenBSD signify tool.
  • Would not remain secure against (improbable) collisions in the Blake2b-512 hash function.

PureEdDSA signatures (default):

  • Require as much memory as the size of the file to sign
  • Cannot be used with files whose size is over 1 Gb
  • Are compatible with all Minisign versions, as well as OpenBSD signify.
  • Would remain secure against (improbable) collisions in the Blake2b-512 hash function.
