Mayelana nalolu hlelo lokusebenza

I-inthanethi iyindawo eyingozi yokushiya idatha yomuntu siqu kanye nemibhalo intanta ingavikelekile; awazi ukuthi umuntu uzozintshontsha nini.
Yingakho sidinga isendlalelo esengeziwe sokuvikela.

Ngalolu hlelo lokusebenza, ungabhala ngemfihlo noma yiluphi uhlobo lwefayela usebenzisa ukubethela kwe-AES-256, okuqine kakhulu!

•Bethela amafayela, izithombe, amavidiyo, umculo, nanoma yiluphi olunye uhlobo lwefayela!

•Ungaphinda ubethele wonke amafolda, udale iphakethe elilodwa elinezinto eziningi ezibethelwe! (Zip ifolda, bese ubhala ngemfihlo ifayela le-zip)

•Ukubethela kanye Nokususwa Kwemfihlo (amafayela akhiqiziwe alondolozwa kufolda efanayo nefayela lokuqala)

UKUBHELWA KWEPHASWEDI

Ukwandisa ukuphepha kwefayela, lolu hlelo lokusebenza luphinde lubethele iphasiwedi, okwenza kube nzima nakakhulu ukuqhekeka.

Ngalesi sizathu, qiniseka ukuthi UKHUMBULA amaphasiwedi akho, noma ungawabhala phansi ukuze uwasebenzise kamuva.

• QAPHELA: Uma ukhohlwa noma ulahlekelwa igama-mfihlo lakho, ngeke ukwazi ukuphinda uthole ukufinyelela kumafayela akho, futhi UNGALAHLEKELWA YIWO Unomphela!
Ngalesi sizathu, qiniseka ukuthi uwanakekela kahle amaphasiwedi akho.

• Iphrothokholi yokubethela ye-AES-256 isezingeni lezempi, okwenza kucishe kungenzeki ukuqhekeka.

Idatha Yezobuchwepheshe:

1. Ama-Cryptographic Algorithms kanye Nezindlela
- Ukutholwa Okubalulekile: I-PBKDF2 ene-HmacSHA256, 100,000 iterations, 16-byte usawoti.
Ifanele ukutholwa kokhiye ovikelekile kuphasiwedi.
- Ukubethela: I-AES-256 kumodi ye-CBC ene-PKCS5Padding kanye ne-16-byte IV ekhiqizwe yi-SecureRandom.
I-AES-CBC ivikelekile uma ihlanganiswe nokuqinisekisa (MAC). Ikhodi isebenzisa i-encrypt-bese-MAC, ngendlela efanele.
- Ubuqotho nobuqiniso: I-HMAC-SHA256 ngaphezu kukasawoti + IV + umbhalo wecipher.
Iqinisekisa ukuvikeleka ekuguqulweni nasekuphazamiseni.
2. Iphasiwedi kanye Nokuphatha Okubalulekile
- Iphasiwedi ifundwe kusixhumi esibonakalayo, ikopishelwe ku-char[], yasetshenziswa, futhi yasulwa ngokushesha ngemva kokusetshenziswa.
- Ukhiye osuliwe uhlukaniswe izingxenye ze-AES ne-HMAC, zisulwe ngemva kokusetshenziswa.
- Ukusula okungafuneki esigabeni sokugcina kuvikela ekuvuzeni kwenkumbulo.
- Qaphela: Ukusula inkambu Ehlelekayo kuchungechunge lwangemuva kungase kungabi kuhle.
3. Ukubethela Nokugeleza Kwesitoreji
- Ibhalela ifayela: usawoti, IV, idatha ebethelwe, ilandelwa yi-HMAC.
- Ilungisa izimvume zefayela ukukhawulela ukufinyelela.
- Ukusetshenziswa okulungile kwemifudlana ukuze ubuyekeze i-HMAC ngesikhathi sokubhala.
4. Ukukhipha ukubethela kanye Nokusakaza Kokuqinisekisa
- Ifunda usawoti kanye ne-IV, ithola okhiye, ibala i-HMAC ukuze iqinisekise ubuqotho ngaphambi kokukhishwa kwekhodi.
- Isebenzisa i-limitedInputStream ukuze ikhawulele ukufunda kubude obufanele bombhalo we-cipher.
- I-Decrypts nge-CipherInputStream, ibhalela ifayela lesikhashana.
- Isusa ngokuphephile ifayela lesikhashana uma kwenzeka iphutha.
- Ihlola ubuqotho ngaphambi kokubhala phezu kwefayela lokugcina.
5. Ukuphatha Okuhlukile kanye Nokuhlanza
- Okuhlukile okukhethekile kusingathwa ngemiyalezo ecacile.
- Ukuhlanza okuguquguqukayo okuzwelayo nokuvalwa kokusakaza okwenziwe esigabeni sokugcina.
