Screenshot of AS-Text Crypt 6.0

Encryption program for text that uses Salsa20, ChaCha20 or HC-256 with a 256-bit key. The program also includes two block ciphers in CTR mode. The program encodes the encrypted information.

Benefits

• In addition to offering HEX, there are also two other encoding methods, one with only letters and one with only symbols.
• Can be used to only encode the text, then leave the field password blank.
• This encryption program makes use of a key strengthening algorithm which delays the final encryption key, this increases the security.
• The program compresses the text to increase the security.
• The program stores an encrypted checksum of the compressed original text, which is verified at decryption.
• You don't need to enter the password twice, instead you can press [F12] if you want to show or hide the password.
• Press [F8] to copy the current text to the clipboard.
