Is your feature request related to a problem? Please describe.

metadata.pubKeyCS used md5 checksum which is outdated.
Replace md5 with sha512 and replace pubKeyCS with pubKeyHash

Describe the solution you'd like

  • When a key is shared, replace the call to generate md5 checksum of sharedWith public key. set medata.pubKeyHash
  • during decryption, verify whether currentAtSignPublicKey's checksum is same as medata.pubKeyHash. Add backward compatibility if pubKeyCS is set using md5 for old data.

Describe alternatives you've considered
