Changes in version 1.2.0 (2026-02-05) - Adds jsonenc() and jsondec() for a minimal JSON encoding/decoding implementation. Changes in version 1.1.1 (2026-01-15) - CBOR: performance optimizations; scalar values with attributes now encode as scalars rather than arrays. Changes in version 1.1.0 (2026-01-08) - Adds cborenc() and cbordec() for CBOR (RFC 8949) encoding/decoding, supporting integers, floats, strings, raw vectors, lists and simple values. - Adds base58enc() and base58dec() for base58 encoding/decoding with a 4-byte double SHA-256 checksum. Changes in version 1.0.5 (2025-03-04) - Package is re-licensed under the MIT licence. Changes in version 1.0.4 (2025-01-16) - base64dec() now errors if convert = TRUE and conversion to a character string fails, no longer returning a raw vector (accompanied by a warning). Changes in version 1.0.3 (2024-10-02) - base64dec() now emits a suppressable warning when failing to convert back to a character string. Changes in version 1.0.2 (2024-09-09) - Improves hash performance in most situations, especially for large files, by optimizing buffer sizes. Changes in version 1.0.1 (2024-07-22) - Improved error message if argument 'convert' is not of logical type. Changes in version 1.0.0 (2024-06-16) - Adds base64 encoding and decoding. - sha3() restricts 'bit' argument to one of 224, 256, 384 or 512. Changes in version 0.5.0 (2024-04-25) - Adds Keccak cryptographic hash algorithm. - Adds shake256() to delineate from sha3(). - Use of sha3() supplying 'bit' argument other than 224, 256, 384 or 512 is deprecated. Changes in version 0.4.0 (2024-04-04) - Adds HMAC generation to sha256(). - Adds SipHash pseudo-random function (PRF) as a fast, cryptographically-strong keyed hash. Changes in version 0.3.0.1 (2024-03-01) - CRAN release correcting for Clang-UBSAN checks. Changes in version 0.3.0 (2024-02-21) - Adds SHA-256 cryptographic hash algorithm. - Folds file hashing into the 'file' argument of the main hash function. Changes in version 0.2.0 (2024-02-01) - Adds file hashing interface. Changes in version 0.1.0 (2024-01-22) - Initial CRAN release. Changes in version 0.0.1 - Initial release to rOpenSci R-universe and Github.
