| 发明名称 | Method for file encryption | ||
| 摘要 | A method for encryption and sealing of a plaintext file by hashing the plaintext file to produce a plaintext hash, encrypting the plaintext file to produce ciphertext, hashing the ciphertext to produce a ciphertext hash, hashing the plaintext hash and the ciphertext hash to produce a result hash, and sealing the ciphertext together with the result hash. This provides verification for non-repudiation and protects against undetected malware corrupting the plaintext or ciphertext files. | ||

| 主权项 | 1. A method for file encryption of a plaintext file, comprising the steps of: hashing the plaintext file to produce a plaintext hash, encrypting the plaintext file to create ciphertext, hashing the ciphertext to produce a ciphertext hash, hashing the plaintext hash and the ciphertext hash to produce a result hash, and sealing the ciphertext together with the result hash, to produce an encrypted file. | ||
