2. H() Deobfuscation Entry Analysis

2.1 Classes with H(Object) Methods

The H() method is the central string deobfuscation function. Each class that defines H() contains its own copy of the decryption algorithm with a unique XOR key derived from the caller's class+method name.

Class	Key Derivation Pattern	Key Construction (bit ops)
AICodeStringUtil	methodName + className	`(1<<3)^3`, `(4<<3)^3`, `(4<<4)^(1<<4)` -> key from stack
AICodeUtils	className + methodName	`(3^5)<<4 ^ 1`, `(3^5)<<4 ^ (1<<1) ^ (3^5)<<4 ^ 3`
Application	methodName + className	`(3^5)<<4 ^ 3`, `(5<<4) ^ (3^5)<<4`
HandleCacheUtil	className + methodName	`(2^5)<<3 ^ (2 dup_x1)`, `(3^5)<<4 ^ 5`
IndentLineUtil	className + methodName	`(5<<4) ^ (2<<1)`, `(4<<5) ^ (3<<2)`
JComponentKt	methodName + className	Same pattern as AICodeStringUtil
Maps	methodName + className	`(2^5)<<3 ^ 5`, `(5<<3) ^ (3^5) ^ 1`
PositionUtil	methodName + className	`(5<<4) ^ (3<<2) ^ 1`, `(5<<3) ^ 4 ^ (5<<4) ^ (3^5)<<1`
PropertyUtils	methodName + className	`(2^5)<<4 ^ 5`, `(1<<3) ^ (3^5) ^ (4<<3) ^ 2`

2.2 H() Algorithm (Common Pattern)

All H() implementations follow the same algorithm:

1. Get caller's class name and method name via LinkageError stack trace
2. Construct key string = methodName + className (or className + methodName)
3. Compute XOR shift constant from bit manipulation on key.length() - 1
4. For each position in the encoded string:
   result[i] = (char)(encoded.charAt(i) ^ key.charAt(keyPos) ^ xorConstant)
   keyPos decrements, wrapping to key.length() - 1 when reaching 0
5. Return new String(result)

2.3 Cross-Class H() Delegation

Classes in this package frequently delegate H() calls to other classes:

Caller	Delegates H() To	Purpose
AICodeUtils	ActionButton.H, LanguageFileExtensionDetails.H, BasicActionsBundle.message	Agent paths, config keys
Application	CodeCompleteService.H, GenericUtils.H	Error messages
EditorCacheUtil	GitReviewService.H, EditorUtils.H	Cache key names
FileSizeUtil	JComponentKt.H	Key name
FileUtil	NewFileUtils.H, IdeAction.H	Directory names (".git", "src")
HandleCacheUtil	FileService.H, IdeAction.H	Error messages
IndentLineUtil	ActionButton.H, FileService.H	Error messages
LogUtil	ActionButton.H, GenericUtils.H	Log category strings
MessageBundle	FontKt.H, HandleCacheUtil.H	Bundle path, error messages
PluginInfoUtils	OverlayUtils.H, Maps.H	Property keys, plugin ID
PropertyUtils	FontKt.H, CodeCompleteService.H	Method prefixes ("set", "get", "is")
VirtualFileUtils	PropertyUtils.H, PositionUtil.H	Path prefixes ("file://", "/")

3. Complete Class Decompilation Details

3.1 AICodeStringUtil (ub)

Type: public final classH() present: YES (methodName + className order)

Public Methods:

H(Object) -> String - Deobfuscation entry
isSpaceOrTab(char, boolean) -> boolean - Checks if char is space/tab (or newline when flag set)
stripLeading(String) -> String - Remove leading whitespace
trailingWhitespace(String) -> String - Extract trailing whitespace
trailingWhitespaceLength(String) -> int - Length of trailing whitespace
leadingWhitespaceLength(String) -> int - Length of leading whitespace
leadingWhitespaceLengthWithTab(String, int) -> int - Leading whitespace with tab size
leadingWhitespace(String) -> String - Get leading whitespace substring
getNextLines(String, int, int) -> List<String> - Get N lines starting from offset
notMatchSuffixIndex(String, String) -> int - Find where suffixes diverge
splitLines(CharSequence) -> String[] - Split text into lines
linesMatch(Iterable, Iterable, boolean) -> boolean - Compare line sequences
createDiffInlays(String, String, boolean) -> List<Pair<Integer,String>> - Create diff inlay markers

Private Methods: V(int), u(String,String), U(TextRanges,int), T(int[]), enum(int), z(int[],int,char,char,TextRanges)

Key Logic: Core string manipulation for diff computation and inlay generation. The createDiffInlays method is critical for inline chat diff rendering.

3.2 AICodeUtils (qb)

Type: public classH() present: YES (className + methodName order)

Public Methods:

getVirtualFile(Project) -> VirtualFile - Get selected editor's virtual file
getOpenFilePathList(Project) -> List<String> - All open file paths

getWasmsDirectoryPath() -> String - WASM directory path
getEditorFromAbsolutePath(Project, String) -> Editor - Editor for file path
getEditor(FileEditorManager, VirtualFile) -> Editor - Find TextEditor for virtual file

H() Calls: ActionButton.H (for "user.home"), LanguageFileExtensionDetails.H (for "aicode-agent"), BasicActionsBundle.message

Key Logic: getAgentDirectoryPath() constructs: System.getProperty("user.home") + / + / + / + BasicActionsBundle.message(H-@!k...). The getPsiMethodContent uses runReadAction to find PsiMethods by line range.

3.3 Application (tb)

Type: public final classH() present: YES (methodName + className order)

Public Methods:

runOnEdtJava(Runnable) -> void - Run on EDT (invokeLater)
runOnEdt(Function0<Unit>) -> void - Kotlin lambda on EDT
runOnPooledThread(Runnable) -> Future<?> - Execute on pooled thread
H(Object) -> String - Deobfuscation

Key Logic: Wraps IntelliJ's ApplicationManager.getApplication() for thread dispatch. The runOnEdt converts Kotlin Function0 to Runnable via InvokeDynamic. Null checks throw via enum(int).

extractContainerType(String) -> String - e.g., List from List<String>
extractClassNameFormMethodId(String) -> String
extractGenerics(String) -> final String

3.13 HighlighterUtil (jb) + Inner Classes

Type: public class

Fields: HIGH_LIGHTER: Key<List<RangeHighlighter>> (created via ConditionalActionConfiguration.H)

float: Logger, byte: Pattern, enum: Pattern

Public Methods:

isTestOfMethod(PsiMethod) -> boolean - Check if method has test annotations
getAllMethods(Project, Document) -> List<UnitTestMethodDto> - All test methods in document
getChangeMethods(List, List, boolean) -> List<UnitTestMethodDto> - Filter by changes
getChangeByDiff(String, int) -> List<ChangeInfoDto> - Parse unified diff
diffContent(List<Change>, Project) -> String - Generate diff content
getTestMethodId(PsiMethod) -> String

Key Logic: Uses runReadAction + executeOnPooledThread for concurrent annotation scanning. Checks for JUnit 5 (@Test), JUnit 4, and TestNG annotations.

3.30 VirtualFileUtils (za)

Type: public classH() present: NO

Public Methods:

from(VirtualFile) -> String - Convert to URI string (handles Windows paths)
getUri(VirtualFile) -> String - Delegate to from()
null(String) -> String - Normalize URI (Windows UNC path handling)

Private Methods:

void(String) -> String - Internal path normalization
const(VirtualFileSystem) -> boolean - Check if local FS (excluding WSL on Windows)

Key Logic: Complex Windows path handling. Converts /C:/ to C:/, handles UNC paths (//server/share), and WSL path detection. Uses PsiUtils.instanceOf for WSL filesystem check.

7. Obfuscation Patterns

7.1 Field Name Obfuscation

The most heavily obfuscated classes use Java reserved keywords as field names:

Class	Obfuscated Fields
CodeCheckUtil	`final`, `try`, `float`, `byte`, `enum`
TypeUtils	`break`, `class`, `true`, `this`, `else`, `char`, `int`, `new`, `long`, `super`, `for`, `if`, `case`, `final`, `try`, `float`, `byte`, `enum`
PluginComponentPanelBuilder	`true`, `this`, `else`, `char`, `int`, `new`, `long`, `super`, `for`, `if`, `case`, `final`, `try`, `float`, `byte`, `enum`
HighlighterUtil$EditorBranchRange	`final`, `try`, `float`, `byte`, `enum`
UnitTestCollectUtil	`float`, `byte`, `enum`

7.2 Method Name Obfuscation

Private methods use single-letter or keyword names:

Class	Obfuscated Methods
AICodeStringUtil	`V`, `u`, `U`, `T`, `z`
AICodeUtils	`p`, `w`, `W`, `y`
ClassNameUtils	`Y`
CodeCheckUtil	`o`
FileUtil	`r`, `M`
HandleCacheUtil	`D`, `a`
HighlighterUtil	`f`, `F`, `m`, `b`, `i`, `j`
IndentLineUtil	`k`
JavaPsiUtils	(mostly unobfuscated)
PsiUtils	`h`, `g`, plus keyword names: `transient`, `throws`, `continue`, `protected`, `native`
ReflectUtil	`implements`, `public`
UnitTestCollectUtil	`throw`, `boolean`, `while`, `abstract`, `package`, `interface`, `double`, `extends`, `private`, `import`, `volatile`, `return`, `do`, `this`
VirtualFileUtils	`void`, `null`, `const`

7.3 Source File Obfuscation

Most classes have 2-letter obfuscated source file names (e.g., "ub", "qb", "tb"). Exceptions:

JavaPsiUtils -> "JavaPsiUtils.java" (unobfuscated, likely auto-generated or less protected)

7.4 enum(int) Pattern

Every class contains a private enum(int) method that serves as a null-check assertion handler. When a null value is detected, enum(int) is called with an error code, which:

Decodes an error message template via H()
Formats it with context-specific arguments
Throws IllegalArgumentException or IllegalStateException
