v0.2.0

Added

• pc_check: :ignore option of Sinetex.open/2: skips the C10 check and picks
  the sender by C13 alone, for counterparties that do not fill C10/C12 with the
  PCs of the certificates. The default (:strict) is unchanged.
• serial: option of Sinetex.Certificate.load/2 and Sinetex.Identity.load/3:
  the number to write in C11/C13, for certificates whose serial number does not
  fit the field or that a counterparty identifies by another number.
• compression_level: option of Sinetex.seal/2. Without it the output is the
  same as before.
• How to read a PKCS#12 file (.pfx, .p12), in the README and the guide.

Changed

• Sinetex.open/2 accepts C07 = 0x00 when the content is not encrypted
  (C04 2, 3, 6 and 10), since there is no symmetric key to select. Other
  invalid values still give 0x04.
• The "empty" header (§5.6.3) is also recognized with the serial number zero
  written as text (32 × "0") in C11 and C13. It still needs
  allow_clear: true.
• inspect/1 of a Sinetex.Error shows the codes in reason as numbers, not
  as a charlist.

v0.1.0

First release, on Hex and HexDocs.

Added

• Sinetex.seal/2 and Sinetex.open/2: Security Protocol v3 (AES-256-GCM) and
  v2 (3DES), every C04 value, the "empty" header (allow_clear: true).
• Sinetex.error_envelope/2 for GEN0004 answers.
• Error table of the manual (Sinetex.Error), with the "lowest code wins" rule.
• Sinetex.Identity and Sinetex.Certificate: PEM and DER, PKCS#1 and PKCS#8
  (also encrypted), the PC code from OU=CSPB-n.
• GZIP and ZIP compression; format detected by magic bytes when receiving;
  output size limit.
• c14_errors: :uniform, trim_padding, known, certificate_check,
  max_input_bytes and max_output_bytes options of Sinetex.open/2.
• Sinetex.Header and Sinetex.Serial for the header format.
• tools/header_dump.exs, to inspect the header of an envelope without keys.
