system, was stored and analyzed in relative secrecy by hundreds of cryptanalysts over a 40-year period starting in the early 1940s. When used correctly, the one-time pad encryption system, which has been used for all the most-secret military and diplomatic communication since the 1930s, is unbreakable. However, due to a serious blunder on the part of the Soviets, some of this traffic was vulnerable to cryptanalysis. The Soviet company that manufactured the one-time pads produced around 35,000 pages of duplicate key numbers, as a result of pressures brought about by the German advance on Moscow during World War II. The duplication—which undermines the security of a one-time system—was discovered, and attempts to lessen its impact were made by sending the duplicates to widely separated users. Despite this, the reuse was detected by cryptanalysts in the US.

is of a length equal to or less than that of a random key, one-time pad encryption is unbreakable. However, cryptanalysis by American code-breakers revealed that some of the one-time pad material had incorrectly been reused by the Soviets (specifically, entire pages, although not complete books), which allowed decryption (sometimes only partial) of a small part of the traffic.
Generating the one-time pads was a slow and labor-intensive process, and the outbreak of war with Germany in June 1941 caused a sudden increase in the need for coded messages. It is probable that the Soviet code generators started duplicating cipher pages in order to keep up with demand.

Results
The NSA reported that (according to the serial numbers of the Venona cables) thousands of cables were sent, but only a fraction were available to the cryptanalysts. Approximately 2,200 messages were decrypted and translated; about half of the 1943 GRU-Naval Washington to Moscow messages were broken, but none for any other year, although several thousand were sent between 1941 and 1945. The decryption rate of the NKVD cables was as follows:
* 1942 1.8%
* 1943 15.0%
* 1944 49.0%
* 1945 1.5%
Out of some hundreds of thousands of intercepted encrypted texts, it is claimed under 3,000 have been partially or wholly decrypted. All the duplicate one-time pad pages were produced in 1942, and almost all of them had been used by the end of 1945, with a few being used as late as 1948. After this, Soviet message traffic reverted to being completely unreadable.
The existence of Venona decryption became known to the Soviets within a few years of the first breaks. It is not clear whether the Soviets knew how much of the message traffic or which messages had been successfully decrypted. At least one Soviet penetration agent, British

, was told about the project in 1949, as part of his job as liaison between British and U.S. intelligence. Since all of the duplicate one-time pad pages had been used by this time, the Soviets apparently did not make any changes to their cryptographic procedures after they learned of Venona. However, this information allowed them to alert those of their agents who might be at risk of exposure due to the decryption.
Significance
The decrypted messages gave important insights into Soviet behavior in the period during which duplicate one-time pads were used. With the first break into the code, Venona revealed the existence of Soviet espionage at

The identification of individuals mentioned in Venona transcripts is sometimes problematic, since people with a "covert relationship" with Soviet intelligence are referenced by cryptonyms. Further complicating matters is the fact the same person sometimes had different cryptonyms at different times, and the same cryptonym was sometimes reused for different individuals. In some cases, notably Hiss, the matching of a Venona cryptonym to an individual is disputed. In many other cases, a Venona cryptonym has not yet been linked to any person. According to authors

Julius and Ethel Rosenberg
Venona has added significant information to the case of Julius and Ethel Rosenberg, making it clear Julius was guilty of espionage, and also showing that Ethel, while not acting as a principal, still acted as an accessory, who took part in Julius's espionage activity and played a role in the recruitment of her brother for atomic espionage.
Venona and other recent information has shown, while the content of Julius' atomic espionage was not as vital to the Soviets as alleged at the time of his espionage activities, in other fields it was extensive. The information Rosenberg passed to the Soviets concerned the

had access to CIA and FBI files, and more damaging, access to Venona Project briefings. When Philby learned of Venona in 1949, he obtained advance warning that his fellow Soviet spy
Donald Maclean was in danger of being exposed. The FBI told Philby about an agent cryptonymed "Homer", whose 1945 message to Moscow had been decoded. As it had been sent from New York and had its origins in the British Embassy in Washington, Philby, who would not have known Maclean's cryptonym, deduced the sender's identity. By early 1951, Philby knew U.S. intelligence would soon also conclude Maclean was the sender, and advised Moscow to extract Maclean. This led to Maclean and Guy Burgess' flight in May 1951 to Moscow, where they lived the remainder of their lives.

One of the considerations in releasing Venona translations was the privacy interests of the individuals mentioned, referenced, or identified in the translations. Some names were not released because to do so would constitute an invasion of privacy. However, in at least one case, independent researchers identified one of the subjects whose name had been obscured by the NSA.
The dearth of reliable information available to the public—or even to the President and Congress—may have helped to polarize debates of the 1950s over the extent and danger of Soviet espionage in the United States.

believes that "Venona remain
an irrefutable resource, far more reliable than the mercurial recollections of KGB defectors and the dubious conclusions drawn by paranoid analysts mesmerized by Machiavellian plots." However, a number of writers and scholars have taken a critical view of the translations. They question the accuracy of the translations and the identifications of covernames that the NSA translations give. Writers Walter and Miriam Schneir, in a lengthy 1999 review of one of the first book-length studies of the messages, object to what they see as the book's overconfidence in the translations' accuracy, noting that the undecrypted gaps in the texts can make interpretation difficult, and emphasizing the problem of identifying the individuals mentioned under covernames. To support their critique, they cite a declassified memorandum, written in 1956 by A. H. Belmont, who was assistant to FBI director J. Edgar Hoover at the time. In the memo, Belmont discusses the possibility of using the Venona translations in court to prosecute Soviet agents, and comes out strongly opposed to their use. His reasons include legal uncertainties about the admissibility of the translations as evidence, and the difficulties that prosecution would face in supporting the validity of the translations. Belmont highlights the uncertainties in the translation process, noting that the cryptographers have indicated that "almost anything included in a translation of one of these deciphered messages may in the future be radically revised." He also notes the complexities of identifying people with covernames, describing how the personal details mentioned for covername "Antenna" fit more than one person, and the investigative process required to finally connect "Antenna" to Julius Rosenberg. The Schneirs conclude that "A reader faced with Venona's incomplete, disjointed messages can easily arrive at a badly skewed impression."
Many of the critiques of the Venona translations have been based on specific cases. The Schneirs' critique of the Venona documents was based on their decades of work on the case of
Ethel and Julius Rosenberg
Julius Rosenberg (May 12, 1918 – June 19, 1953) and Ethel Rosenberg (; September 28, 1915 – June 19, 1953) were American citizens who were convicted of spying on behalf of the Soviet Union. The couple were convicted of providing top-secret i ...
. Another critique of the Venona translations came from the late Rutgers University law professor John Lowenthal, who as a law student worked as a volunteer for Alger Hiss's defense team, and later wrote extensively on the
Hiss case
Alger Hiss (November 11, 1904 – November 15, 1996) was an American government official accused in 1948 of having spied for the Soviet Union in the 1930s. Statutes of limitations had expired for espionage, but he was convicted of perjury in con ...
. Lowenthal's critique focused on one message (Venona 1822 KGB Washington-Moscow 30 March 1945), in which the comments identified the covername 'Ales' as "probably Alger Hiss." Lowenthal raised a number of objections to this identification, rejecting it as "a conclusion psychologically motivated and politically correct but factually wrong." Lowenthal's article led to an extended debate on the 'Ales' message, and even prompted the NSA to declassify the original Russian text. Currently, Venona 1822 is the only message for which the complete decrypted Russian text has been published.

Commenting on the list of 349 Americans identified by Venona, published in an appendix to ''Venona: Decoding Soviet Espionage in America'', Navasky wrote, "The reader is left with the implication—unfair and unproven—that every name on the list was involved in espionage, and as a result, otherwise careful historians and mainstream journalists now routinely refer to Venona as proof that many hundreds of Americans were part of the red spy network."
[ Navasky goes further in his defense of the listed people and has claimed a great deal of the so-called espionage that went on was nothing more than "exchanges of information among people of good will" and that "most of these exchanges were innocent and were within the law."]
