XML Encryption is different from and unrelated to Transport Layer Security (TLS), which is used to send encrypted messages (including XML content, both encrypted and otherwise) over the internet. Jager & Somorovsky (2011) reported that this specification has severe security concerns.
With the advent of computing, the term plaintext expanded beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without requiring a key or other decryption device. Information—a message, document, file, etc.—if to be communicated or stored in an unencrypted form is referred to as ...
As the file format is a group of XML files within a ZIP; unzipping, editing, and replacing the workbook.xml file (and/or the individual worksheet XML files) with identical copies in which the unknown key and salt are replaced with a known pair or removed altogether allows the sheets to be edited.

One example of deniable encryption is a cryptographic filesystem that employs a concept of abstract "layers", where each layer can be decrypted with a different encryption key. [ citation needed ] Additionally, special " chaff layers" are filled with random data in order to have plausible deniability of the existence of real layers and their ...
Because VTD-XML keeps the XML text intact without decoding, when an application intends to modify the content of XML it only needs to modify the portions most relevant to the changes. This is in stark contrast with DOM, SAX, or StAx parsing, which incur the cost of parsing and re-serialization no matter how small the changes are.
The Web Cryptography API is the World Wide Web Consortium’s (W3C) recommendation for a low-level interface that would increase the security of web applications by allowing them to perform cryptographic functions without having to access raw keying material. [1]
PKCS #7 files may be stored both as raw DER format or as PEM format. PEM format is the same as DER format but wrapped inside Base64 encoding and sandwiched in between ‑‑‑‑‑BEGIN PKCS7‑‑‑‑‑ and ‑‑‑‑‑END PKCS7‑‑‑‑‑. Windows uses the .p7b file name extension [6] for both these encodings.
In an asymmetric key encryption scheme, anyone can encrypt messages using a public key, but only the holder of the paired private key can decrypt such a message. The security of the system depends on the secrecy of the private key, which must not become known to any other.
