rust-crypto is unmaintained; switch to a modern alternative

Details
Status	unmaintained
Package	rust-crypto
Version	0.2.36
URL	DaGenix/rust-crypto#440
Date	2016-09-06

The rust-crypto crate has not seen a release or GitHub commit since 2016,
and its author is unresponsive.

NOTE: The (old) rust-crypto crate (with hyphen) should not be confused with
similarly named (new) RustCrypto GitHub Org (without hyphen). The GitHub Org
is actively maintained.

We recommend you switch to one of the following crates instead, depending on
which algorithms you need:

• dalek-cryptography GitHub Org:
  • Key agreement: x25519-dalek
  • Signature algorithms: ed25519-dalek
• ring:
  • AEAD algorithms: AES-GCM, ChaCha20Poly1305
  • Digest algorithms: SHA-256, SHA-384, SHA-512, SHA-512/256 (legacy: SHA-1)
  • HMAC
  • Key agreement: ECDH (P-256, P-384), X25519
  • Key derivation: HKDF
  • Password hashing: PBKDF2
  • Signature algorithms: ECDSA (P-256, P-384), Ed25519, RSA (PKCS#1v1.5, PSS)
• RustCrypto GitHub Org:
  • AEAD algorithms: aes-gcm, aes-gcm-siv, aes-siv, chacha20poly1305, xsalsa20poly1305
  • Block ciphers: aes, cast5, des
  • Digest algorithms: sha2, sha3, blake2, ripemd160
    (legacy: sha-1, [md-5])
  • Key derivation: hkdf
  • MACs: cmac, hmac, pmac, poly1305
  • Password hashing: pbkdf2
  • Stream ciphers: aes-ctr, chacha20, hc-256, salsa20
• secp256k1:
  • Key agreement: ECDH (secp256k1 only)
  • Signature algorithms: ECDSA (secp256k1 only)
• sodiumoxide:
  • AEAD algorithms: ChaCha20Poly1305 (IETF version)
  • Digest algorithms: SHA-256, SHA-512
  • HMAC
  • Key agreement: X25519 + BLAKE2b
  • Password hashing: Argon2(i/d), scrypt
  • Public key encryption: NaCl "Box" (X25519 + XSalsa20Poly1305)
  • Signature algorithms: Ed25519
  • Short-input PRF: SipHash24
• orion:
  • AEAD algorithms: ChaCha20Poly1305 (IETF version), XChaCha20Poly1305
  • Digest algorithms: SHA-512, BLAKE2b
  • Key derivation: HKDF
  • MACs: HMAC, Poly1305
  • Password hashing: PBKDF2
  • Stream ciphers: ChaCha20 (IETF version), XChaCha20

Seems rust-crypto recently became a dependency. It was necessary to implement transaction signing #345. That code will most likely change a lot in the near future so maybe we can just replace this crate with another.
