CHANGELOG

4.0.0 (⚠️ BREAKING ⚠️) - 8/29/2026

• Migrated from openssl to using native scrypt which uses AES-256-CTR for encryption with HMAC-SHA256 authentication. Most certainly is not backward compatible with encrypted files using the previous versions of openssl aes-256-cbc.

3.0.0 - 10/31/2025

• Use shred instead of rm -f when optionally deleting original file. Requires that the shred command is installed.

2.4.0 - 7/3/2025

• Support for printing plaintext to stdout when decrypting file via flag --stdout.
• Bump copyright year to 2025.

2.3.0 - 7/30/2024

• Prompt to confirm deleting original file when invoking encrypt.

2.2.0 - 7/10/2020

• Append .aes file extension instead of substituting when encrypting.
• Use derivation function (-pbkdf2) when encrypting. See pull request.

2.1.1 - 3/25/2019

• Updated the notice text when using environment variable CRYPTR_PASSWORD for the password.
• Updated tests/test.bash.
• Bump copyright year to 2019.

2.1.0 - 10/4/2017

• You may now define the password to use when encrypting and decrypting using the CRYPTR_PASSWORD environment variable. This change enables non-interactive/batch operations.

• Added a test script tests/test.bash.

2.0.1 - 10/2/2017

• Small optimization, removed unneeded function cryptr_info().

2.0.0 - 10/2/2017

BREAKING CHANGE

• Increased the OpenSSL key size to 256bit from 128bit. Any files encrypted with version 1.0.0 must be decrypted with version 1.0.0.

1.0.0 - 10/1/2017

• Initial release.
