Topic: Cleartext


  
  Cleartext - Wikipedia, the free encyclopedia
In data communications, cleartext is the form of a message or data which is transferred or stored without cryptographic protection.
For example, "The keys in the Foo protocol are exchanged as cleartext." would mean that the keys are not encrypted during transmission.
Cleartext material is sometimes in plain text form, meaning a sequence of characters without formatting, but this is not strictly required as the sense is 'no protection from snooping', not 'no special software required to read'.

 Cleartext - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-05)
In telecommunications, particularly data communications, cleartext is the form of a message or data which is transferred or stored without cryptographic protection.
Thus, "The keys in the FOO protocol are exchanged as cleartext.
That's so insecure it's a crock." To be fair, the FOO protocol might have been intended only for use over a secure channel and the fact that messages (ie, keys) are passed as cleartext might not be thought a problem.

 Method for obtaining a securitized cleartext attestation in a distributed data processing system environment - Patent ...
Encryption is an operation that involves converting cleartext information into encrypted information to render it unintelligible by any subject unaware of the mathematical encryption function F and/or the encryption key attached to this function by which the cleartext information is converted into encrypted information.
Cleartext data stations, whether signed or sealed, are definitely protected against forgery (since no one can reproduce the signature other than the person who has the private key or secret key and no one other than the recipient can reproduce the seal) but are not protected against theft during transfer.
This supplementary protection datum is in cleartext, like the rest of the information in the attestation, and not kept confidential as in the attestation protection system defined by the aforesaid ECMA Standard 138, another difference being of course the fact that the protection datum is internal to the attestation instead of being external.

 NSNL 4 - Crypto Codes   (Site not responding. Last check: 2007-11-05)
In an ordered code, the cleartext entries are listed alphabetically and the codegroups are allotted to these entries in numerical order - in case the codegroups consists of figures - or in alphabetical order - in case the codegroups consists of letters.
Both encoding and decoding are easily done with the same book, since both cleartext and codegroups follow in their normal order.
In one the cleartext is listed in alphabetic order together with the codegroups in their mixed order.

Dash escaped cleartext is the ordinary cleartext where every line starting with a dash '-' (0x2D) is prefixed by the sequence dash '-' (0x2D) and space ' ' (0x20).
The message digest is computed using the cleartext itself, not the dash escaped form.
As with binary signatures on text documents, a cleartext signature is calculated on the text using canonical line endings.

 Core Frogbit Algorithm Explanations
Let us assume that a bit-serial cleartext message is encrypted into ciphertext by a sender, and that a session key is established for this purpose (we ignore attacks based on different messages that could be encrypted with the same key).
An adversary is given the opportunity to modify the ciphertext bits in transit from the sender to the receiver.
So the data integrity protection may be provided by the Frogbit cipher with some cleartext message redundancy which should allow the receiver party to detect any such message randomization with high probability.

 WSE 2.0 Authentication: How To Avoid ClearText Passwords With UsernameToken
For each user, he stores a randomly generated salt value and a hash of the cleartext password combined with salt value.
The downside to this approach is that the salt is sent across the wire in clear text.
From what I can see the only soltions appear to be to have the password unhashed in the DB and protect it with SQL encryption and SQL security, or only accept plain text passwords from WSE.

 Appropriate?   (Site not responding. Last check: 2007-11-05)
Cryptograms are deduced from the cipher and the cleartext.
This is to say, given a cleartext we can turn it into a cryptogram (also called ciphertext) by using the cipher.
If both cryptogram and cipher are required to deduce the cleartext, from the cryptogram alone we obviously cannot deduce both the cleartext and the cipher.

 Re: cleartext signatures - trailing white space - proposal
I would modify Werner's proposed text like so, for grammatical clarity: When calculating a cleartext signature, trailing whitespace (defined as the characters (0x20), (0x09), (0x0D) and (0x0A)) at the end of any line shall be removed and replaced by the sequence for the purpose of calculating the cleartext signature.
This protects against a failure of a valid signature due to many conversions that may occur in text editing tools or in transport.
I think it is important to clarify both the definition and a little of the reasoning behind this for readers and implementers of the RFC.

The DUT receiving cleartext packets from the tester encrypts the packet and forwards it to the second DUT on one of the N interfaces inter-connecting the two DUTs.
Latency for store-and-forward devices is defined as the time interval starting when the last bit of the input cleartext frame reaches the input port of the encrypting DUT and ending when the first bit of the output cleartext frame is seen on the output port of the decrypting DUT.
For cut-through or bit-forwarding devices, latency is defined as the time interval starting when the first bit of the input cleartext frame reaches the input port of the encrypting DUT and ending when the first bit of the cleartext output frame is seen on the output port of the decrypting DUT.

 Appendix E | The Digital Dilemma: Intellectual Property in the Information Age | Committee on Intellectual Property ...
For instance, if the cleartext is "OneIfBy" and the key is "CallMeIshmael," the first character of the key ("C") would indicate that the "O" should be shifted right by 3 (to become "R"), the "n" shifted right by 1 (to become "o"), and so on.
Unfortunately, it is usually impractical to use a one-time pad, because its security depends on a new key being generated and used each time a new message is encrypted; this means that the total number of key bits is too large to be practical.
That is, it is infeasible for anyone to infer any information about the cleartext from the ciphertext, even if that person has access to the key generation, encryption, and decryption procedures.

 The Birthday Problem and OFB   (Site not responding. Last check: 2007-11-05)
There is no feedback from either the cleartext or the ciphertext to the DES junk.
Therefore, the DES encipherer and connected equipment merely generates a stream of binary data which is added to the cleartext to get the ciphertext to encipher, and added to the ciphertext to get the cleartext to decipher.
Now assume any different cleartext-there exists a key that will decipher that ciphertext to this cleartext, namely the stream of bits that is equal to the bit-by-bit exclusive-or sum of the ciphertext and that different cleartext.

 Zvon - RFC 1827 [IP Encapsulating Security Payload (ESP)] - ENCAPSULATING SECURITY PROTOCOL PROCESSING
If strict red/fl separation is being enforced, then the addressing and other information in the cleartext IP headers and optional payloads MAY be different from the values contained in the (now encrypted and encapsulated) original datagram.
If decryption succeeds, the original transport-layer (e.g., UDP, TCP, ICMP) frame is removed from the (now decrypted) ESP. The information from the cleartext IP header and the now decrypted transport-layer header is jointly used to determine which application the data should be sent to.
This might be valid because the cleartext IP headers might have a different classification level after the data has been encrypted using ESP.

The new API would have one other benefit: by cleanly separating cryptographic from I/O operations, it might make the innards of OpenSSL significantly cleaner and easier to understand.
The new API would be event-driven, that is, the application and the API would pass each other events; each event would be either an SSL Record Layer record (aka protocol data unit), a block of cleartext, or a crypto engine processing request.
Cleartext I/O events as seen by the state machine are simply batches of bytes on their way into the API from the app or out of the API to the app, stored in the following structure:
