Crate signcryption

Structs

• Keypair
  A signcryption keypair used to sign, verify and encrypt messages.
• SignCrypt
  Data structure containing the ciphertext, signature and additional data
• SignState
  Used to hold intermediate values during the signcryption process.

Enums

• Curve
  The curve used, variants are Ristretto255 or Edwards25519. Ristretto255 is recommended and the default variant.
• SignCryptError
  Signcryption failure modes

Constants

• SECRETKEYBYTES
  Length of the secret key
• SEEDBYTES
  Length of the seed for keypair creation
• SHAREDBYTES
  Length of the generated shared secret
• SIGNBYTES
  Length of the resulting signature
