# How do I become a cryptographer?

## How do I become a cryptographer?

To become a cryptographer you must first earn a bachelor’s degree in computer science, information technology, cybersecurity, or mathematics. All of these disciplines teach the technical, quantitative, and logic skills needed for making and breaking complex computerized codes.

## Is it possible to break RSA encryption?

It would take a classical computer around 300 trillion years to break a RSA-2048 bit encryption key.

**Is the RSA credible?**

RSA is secure, but it’s being implemented insecurely in many cases by IoT manufacturers. More than 1 in every 172 RSA keys are at risk of compromise due to factoring attacks. ECC is a more secure alternative to RSA because: ECC keys are smaller yet more secure than RSA because they don’t rely on RNGs.

### Is being a cryptographer hard?

Cryptography is a field that combines three different subjects; mathematics, computer science, and information security. As such, it can be very hard to learn, especially if you have little or no knowledge of the aforementioned subjects.

### What degree is needed to be a cryptologist?

Pursue a bachelor’s degree: To obtain a job as a cryptologist, employers will generally require, at the minimum, a bachelor’s degree in mathematics, computer science, or a related field.

**How long does it take to become a cryptographer?**

Most cryptography jobs require at least five years of experience in computer and information technology security. Entry-level positions as software programmers, information security analysts, or computer system analysts build familiarity with information technology security hardware and software.

#### What kind of math is used in cryptography?

Most encryption is based heavily on number theory, most of it being abstract algebra. Calculus and trigonometry isn’t heavily used. Additionally, other subjects should be understood well; specifically probability (including basic combinatorics), information theory, and asymptotic analysis of algorithms.

#### Why become a fellow of the RSA?

Fellows are committed to inspiring better ways of thinking, acting and delivering change. An integral part of the RSA in creating a better future, Fellows champion new ideas, drive social change, deliver practical solutions and support the RSA mission.

**Why is RSA obsolete?**

The problem with RSA is that as these keys get longer, the increase in security isn’t commensurate to the increase in computational power it takes to use them. It’s just not sustainable. The CAB Forum just mandated that keys used for signing software must now be at least 3072-bit in length if you’re using RSA.
