+# Task 1
+
+## Commit Signing
+
+Commit signing is a way to cryptographically verify the identity of the author of a commit. Git supports multiple signing methods, including GPG and SSH keys. The signature is embedded in the commit and verified by platforms like GitHub and Bitbucket, which display a verification status (such as "Verified").
+
+## Benefits of SSH Signing
+
+### 1. Simple Setup
+
+- SSH keys are already widely used for authentication with remote repositories.
+- Does not require installing or configuring GPG, which can be complex, especially on Windows.
+- Creating and adding SSH keys is quick and straightforward.
+
+### 2. Enhanced Trust and Security
+
+- Signed commits prove that the commit was created by a specific person (the SSH key owner).
+- Helps prevent history tampering or malicious impersonation.
+
+### 3. Platform Integration
+
+- GitHub displays the signature status directly in pull requests and commit history.
+- Commit signing can be enforced via branch protection rules.
+- Bitbucket Server and Data Center (starting with version 8.8) also support SSH commit verification.
+
+### 4. Reuse of Existing Keys
+
+- The same SSH keys that are already used for repository access can be used again.
+- No need to manage a separate GPG key.
+
+### 5. Compliance and Audit Support
+
+- Signed commits create a cryptographically verifiable trail of changes.
+- Facilitates auditability and helps meet security and compliance requirements.
+
+## Conclusion
+
+Using SSH commit signatures is a  convenient way to prove authorship of code changes. It is especially valuable in collaborative development, open source projects, and environments with strong security requirements.

+# Task 2
+
+## Standard Merge
+
+Creates a merge-commit and saves the change log of all branches
+
+### Pros:
+
+- Stores the full log of changes
+- Is convenient for collaborative environments
+
+### Cons:
+
+- A large volume of merge-commits can clutter the commit history
+
+## Squash and Merge
+
+Combines all the commits in a branch before merging
+
+### Pros:
+
+- Increased history readability
+
+### Cons:
+
+- Information about intermediate commits is lost
+
+## Rebase and Merge
+
+Applies all commits over the base branch
+
+### Pros:
+
+- Linear history with no merge commits
+
+### Cons:
+
+- Can be dangerous in collaborative environments
+
+## Why Standard Merge is Prefered
+
+Because it:
+
+- Saves the full commit history
+- Allows for an easy management of who and when applied what changes
+- Does not rewrite history, making it safe for collaborative projects
