Conventional modes of algorithms typically include deterministic algorithms, which produce the same output for a given input every time, and probabilistic algorithms, which incorporate randomness and may yield different outcomes on different runs. Other common types are recursive algorithms, which solve problems by breaking them down into smaller subproblems, and iterative algorithms, which use loops to repeat operations until a condition is met. Additionally, there are greedy algorithms that make locally optimal choices at each step, and divide-and-conquer algorithms that tackle problems by dividing them into smaller, more manageable parts.
Algorithms can be classified in several ways, including by their design paradigm, such as divide and conquer, dynamic programming, greedy algorithms, and backtracking. They can also be categorized based on their purpose, such as search algorithms, sorting algorithms, and optimization algorithms. Additionally, algorithms can be distinguished by their complexity, specifically time complexity and space complexity, to evaluate their efficiency. Lastly, they may be classified based on their application domains, such as machine learning algorithms, cryptographic algorithms, and graph algorithms.

The Java Cryptography Architecture (JCA) is a framework for working with cryptography using the Java programming language. It forms part of the Java security API, and was first introduced in JDK 1.1 in the java.security package.http://en.wikipedia.org/wiki/Java_Cryptography_Architecture
No. SPIHT and JPEG are two different compression algorithms.
There are two types of cryptography algorithms: 1) Public key cryptography 2) Secret key cryptography
Encryption and decryption algorithms are called ciphers in cryptography
Cryptography is the study of hiding information using mathematical algorithms in such a way that the original information cannot be assertained from the resulting 'cyphercode' without knowledge of the specific 'key' required to undo the changes made by the algorithm.The algorithms used in cryptography are related to math, being mathematically founded, and so, by extension, cryptography is related to math.
Math algorithms are complex and can easily be broken
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
There are 2 types of cryptography such as: 1- Symmetric-key or Secret key Cryptography 2- Asymmetric-key or Public key Cryptography

One might need cryptography in any situation which warrants privacy or secrecy to protect data, trade secrets, or embarrassing situations. Examples include business transactions, ecommerce, extramarital affairs, political campaigns, and government actions.
The option that is not a disadvantage of symmetric cryptography is "speed." In fact, symmetric cryptography is generally faster than asymmetric cryptography because it uses simpler algorithms and smaller key sizes for encryption and decryption. The other options—lack of true sender authentication and the risk of compromising multiple parties if one key is broken—are indeed disadvantages of symmetric cryptography.
To become a cryptogratist, start by developing a strong foundation in mathematics and computer science, particularly in areas like algorithms and data structures. Familiarize yourself with cryptography principles, including encryption methods and security protocols, through online courses or textbooks. Engage in practical projects, such as creating your own encryption algorithms or participating in cryptography challenges, to gain hands-on experience. Networking with professionals in the field and staying updated on the latest research and developments in cryptography is also essential.
It seems like there may be a typo in your question. If you are referring to "character permutation," it typically refers to rearranging the order of characters in a string to create different combinations. This can be useful in algorithms and cryptography for generating unique sequences or codes.
