PlexCrypt will protect documents and folders based on both asynchronous encryption based on Public-Key-Infrastructure (PKI) and synchronous encryption based on passwords.

The encryption uses secured algorithms such as AES, Blowfish,

CAST, DES, ElGamal, IDEA, IES, RC4, RC6, RSA, Rijndael, Serpent Skipjack, Twofish, etc. It allows users to encrypt multiple files and folders automatically. PlexCrypt allows users to digital sign documents and folders and use that signature to verify that original document has not been maliciously or accidently altered.

PlexCrypt can create self-decrypting files, which can be transfered to other users and can be decrypted without installing PlexCrypt. PlexCrypt can also shred or deletes documents securely. It supports MD5WithRSAEncryption, SHA1WithRSA/ISO9796-2, MD2WithRSAEncryption, RIPEMD160WithRSAEncryption,

SHA1WithRSAEncryption, RIPEMD160WithRSAEncryption,

MD5WithRSA/ISO9796-2 RIPEMD160WithRSA/ISO9796-2,

RIPEMD160WithRSA/ISO9796-2 algorithms for digital signatures.

PlexCrypt also allows users to archive a set of files and folders in

the ZIP format and extract them later. In addition, it allows users to create and manage digital certificates and key-pairs for encryption and digital signatures.
