v0.1.0

Added

• PKCS12.decode/3 and PKCS12.decode!/3: read a PKCS#12 file and return the
  private key, its certificate, the other certificates, every bag with its
  attributes, and the algorithms the file uses.
• Encryption: PBES2 with AES-CBC, 3DES or DES, and the PKCS#12 ciphers (3DES,
  2-key 3DES, RC2-40, RC2-128, RC4). RC2 is implemented by the library.
• Integrity: the classic MAC with SHA-1 to SHA-512, and PBMAC1 (RFC 9879).
• BER input, and the password encodings of tools that differ from RFC 7292.
• Limits on the key derivation work (:max_iterations,
  :max_total_iterations) and verify_mac: false.
• PKCS12.encode/3 and PKCS12.encode!/3: write a PKCS#12 file from a key
  (PrivateKeyInfo in DER, or a key record of :public_key), its certificate
  and other certificates. The :modern profile (default) uses AES-256-CBC
  with PBKDF2-HMAC-SHA-256 and a SHA-256 MAC, with 100,000 iterations; the
  :legacy profile, 3DES and RC2-40 with a SHA-1 MAC. Options choose each
  algorithm, PBMAC1, the iteration count, friendlyName and localKeyId.
