Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce. Modern cryptography techniques include algorithms and ciphers that enable the encryption and decryption of information, such as 128‑bit and 256‑bit encryption keys. Modern ciphers, such as the Advanced Encryption Standard (AES), are considered virtually unbreakable.
A common cryptography definition is the practice of coding information to ensure only the person that a message was written for can read and process the information. This cybersecurity practice, also known as cryptology, combines various disciplines like computer science, engineering, and mathematics to create complex codes that hide the true meaning of a message. Cryptography can be traced all the way back to ancient Egyptian hieroglyphics but remains vital to securing communication and information in transit and preventing it from being read by untrusted parties. It uses algorithms and mathematical concepts to transform messages into difficult‑to‑decipher codes through techniques like cryptographic keys and digital signing to protect data privacy, credit card transactions, email, and web browsing.
Cryptography remains important to protecting data and users, ensuring confidentiality, and preventing cyber criminals from intercepting sensitive corporate information. Individuals and organizations use cryptography on a daily basis to protect their privacy and keep their conversations and data confidential. The technique ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted. It also secures browsing, such as with virtual private networks (VPNs), which use encrypted tunnels, asymmetric encryption, and public and private shared keys.
Similar to how cryptography can confirm the authenticity of a message, it can also prove the integrity of the information being sent and received. The technology also ensures information is not altered while in storage or during transit between the sender and the intended recipient. For example, digital signatures can detect forgery or tampering in software distribution and financial transactions.Cryptography confirms accountability and responsibility from the sender of a message, which means they cannot later deny their intentions when they created or transmitted information. Digital signatures are a good example of this, as they ensure a sender cannot claim a message, contract, or document they created to be fraudulent. Furthermore, in email nonrepudiation, email tracking makes sure the sender cannot deny sending a message and a recipient cannot deny receiving it.
There are many types of cryptographic algorithms available. They vary in complexity and security, depending on the type of communication and the sensitivity of the information being shared.

Nesse sentido, julgue os itens a seguir em relação às contribuições da literatura infanto-juvenil:
I.O contato com a literatura infanto-juvenil estimula uma maior aptidão para a aprendizagem.
II.Contribui para o desenvolvimento da autonomia e da criatividade.
III.Desenvolve as habilidades de ler, interpretar e escrever textos.
IV.Acumula repertório significativo de leituras que contribuirá para a formação de argumentos e opiniões.
É CORRETO o que se afirma em:
Criar condições para o ________ de todas as crianças, considerando, também, as possibilidades de aprendizagem que apresentam nas diferentes faixas etárias.
Assinale a alternativa que completa corretamente a lacuna do fragmento:
Éticos: da autonomia, da responsabilidade, da solidariedade e do respeito ao bem comum, ao meio ambiente e às diferentes culturas, identidades e singularidades;
Políticos: dos direitos de cidadania, do exercício da criticidade e do respeito à ordem democrática e
Estéticos: da sensibilidade, da criatividade, da ludicidade e da liberdade de expressão nas diferentes manifestações artísticas e culturais (BRASIL, 2009, p. 2).
Esses princípios estão vinculados à Base Nacional Comum Curricular por meio da definição de seis direitos de aprendizagem e desenvolvimento (Conviver, Brincar, Participar, Explorar, Expressar e Conhecer-se.) os quais pretendem assegurar as condições para que as crianças aprendam em situações nas quais possam desempenhar um papel ativo em ambientes que as convidem a vivenciar desafios e a sentirem-se provocadas a resolvê-los, nas quais possam construir significados sobre si, os outros e o mundo social e natural (BRASIL, 2017, p. 35).
Considerando tais abordagens, os direitos de conhecer -se e conviver relacionam-se aos princípios:
(__)Contribui na aprendizagem e conhecimento da criança. (__)Possibilita criatividade, interação social e crescimento sadio. (__)Desenvolve o potencial cognitivo, motor e social.
Após análise, assinale a alternativa que apresenta a sequência CORRETA dos itens acima, de cima para baixo:
I.À vida e à saúde. II.À alimentação, à educação, ao esporte. III.Ao lazer, à profissionalização, à cultura. IV.À dignidade, ao respeito, à liberdade e à convivência familiar.
É CORRETO o que se afirma em:
I.Desenvolver o educando.
II.Assegurar a formação comum indispensável para o exercício da cidadania.
III.Fornecer meios para progredir no trabalho e em estudos posteriores.
IV.Formação técnica para o desenvolvimento de habilidades do campo profissional.
Está CORRETO o que se afirma em:
Assinale a alternativa que preenche corretamente as lacunas.
"[...] aplica-se na construção dos processos de ensino e aprendizagem e orienta a escolha de objetivos e conteúdos, visando a ampliar as relações entre os conhecimentos da cultura corporal de movimento e os sujeitos da aprendizagem. Busca-se legitimar as diversas possibilidades de aprendizagem que se estabelecem com a consideração das dimensões afetivas, cognitivas, motoras e socioculturais dos alunos."
