Aloaha PDF Crypter protects PDF documents with public-key encryption, so access depends on a recipient having the matching private key rather than knowing a shared PDF password. Its FileCrypter function applies the same method to other files, using public keys from an address book or Windows certificate store. Encrypted files can be decrypted by recipients with a valid matching key. The program is intended for secure document exchange and ebook distribution.

Aloaha PDF Crypter is a Windows utility for protecting PDF documents and other files with public-key encryption. It is intended for people distributing sensitive documents or ebooks who need access to depend on recipient certificates rather than a shared PDF password. The sender selects the public keys of the people allowed to open a file; recipients need a matching private key installed in the Windows certificate store to decrypt it.
For PDFs, the program encrypts the document for selected certificate holders. This offers a different control from conventional owner and user passwords: forwarding the encrypted file does not give another person the ability to read it unless that person has an appropriate private key. The resulting PDF is PDF 1.5 compatible and can be opened with Adobe Reader 6 or later, provided the recipient can decrypt it with a valid key.
The companion FileCrypter function applies the same public-key approach to documents beyond PDF. It encrypts files for a list of public keys drawn from the user's address book or certificate store. A recipient can decrypt the file when at least one corresponding valid private key is installed in their Windows certificate store. This supports sending encrypted files to several recipients without distributing a shared password.
Typical uses include controlled ebook distribution, exchanging confidential documents, and sealing files for named recipients. Certificate-based encryption helps limit access to the intended key holders, but it does not prevent an authorized recipient from copying or sharing content after opening it. Recipients also need to retain access to the relevant private key; without it, the encrypted document cannot be read.
Aloaha PDF Crypter is freeware for Windows. Its interface is available in English, Dutch, German, and Italian. The stated platform support includes Windows editions from Windows 2000 through Windows 10, along with Windows Server and other Windows versions.
